Update:
IMPORTANT NOTE: TO FIT MORE EYESHADOWS INTO YOUR 15X PALETTE, POP OUT THE PLASTIC DIVIDER TO FIT 21 EYESHADOWS INSTEAD OF 15.
I have a very, very large collection of MAC eyeshadow singles and pigments that recently I got tired of seeing scattered everywhere on my makeup table and having to sort through each eyeshadow one by one.
The solution? These 15-pan palettes. I have three of these. One of them includes neutral colors: Vanilla, Dazzlelight, Brule, Naked Lunch, All That Glitters, Expensive Pink, Woodwinked, Satin Taupe, Wedge, Cork, Amber Lights, Bronze, Charcoal Brown, Espresso, and Carbon.
My second one includes shades that I only use for special occasions and my dance costumes: Cranberry, Beautymarked, Antiqued, Goldmine, Electra, Knight Divine, Chrome Yellow, Sumptious Olive, Humid, Red Brick, Orange, Passionate, Electric Eel, Satellite Dreams, and Nocturnelle.
My third one includes pigments that I pressed into the pans.
And I love these palettes to death! I don't know how I'd live without them!
I mainly use them for my dance costumes and special occasions since I don't like wearing eyeshadow during regular hours/days, but these palettes are great for any purpose.
It comes in a slim, sturdy black plastic case that doesn't break. When you order it, it comes with the palette itself and 15 eyeshadows/Pro Refill Pans that you have to assemble yourself. There's no mirror or clear tops (no bells and whistles, you could say), but that's perfectly fine. Me being a busy dancer in a dance company that performs nationally, these are very travel-friendly and especially useful for someone always on-the-go like me. I feel comfortable enough to use these on a plane, charter bus, and basically any car.
It might seem like the $188.50 price tag is expensive, but purchasing this versus purchase 15 seperate eyeshadows will save you $66.50. If you're a heavy MAC eyeshadow user or you're just sick of having to sort through each eyeshadow single one by one, these palettes will be a life-saver for you. Definitely worth investing in!
Would I repurchase? Yes.

expensive for a basic palette, but excellent quality, you get what you pay for... once you depot your MAC shadows this baby will pay for itself in sleek storage. easy to pop into your bag and/or great for travel. also can put other shadows in here (pan has to be same size). Also can pop off the divider and make even more room for pans

Love love love. I pop out the top so I can fit more shadows. I have Mac refills/singles, nyx singles and urban decay eyeshadows in my current palette. Def would repurchase more.

I bought one a while ago when on a trip to London, each palette refill is about €11.50 which compared to €14 for a regular eyeshadow, you're saving so much more by buying the palette and the refills. The palettes are about €15, which is steep, but by buying the refills, you'll have got your moneys worth back from not buying the regulare eyeshadows, so it is worth it! I've already completed my first Mac palette, and already thinking of buying another 2, and possibly de-potting my eyeshadows into a palette and using the old packaging for Back 2 Mac :)

OK I admit it - I seem to have a bit of a palette obsession going on! I have 2 Inglot 10s, a Make Up For Ever 12 (I think?), a FACE Atelier 12, 3 MAC 4s, 1 MAC Blush and 3 (soon to be 4, as they're full!) MAC 15s. I know about palettes!
While the MAC were my first, and I do really like them, I'm not sure they're my favourite.
Pro: They are the easiest to move pans around - most other brands press in so are difficult to shuffle round, I find these generally pop out quite easily. They're also very slim and light. Inglot are heavy. Make Up For Ever long. They're easy to open and close and I have travelled well with mine many times.
Con: Smallest eyeshadow pans of all (Face Atelier are the same size to be fair). Can't distinguish between palettes when closed (Inglots lids are opaque and Face Ateliers clear). Can't identify shade name when in (this is a problem with all palettes).
None of my palettes have a mirror in the lid or space to hold brushes etc.
Think my next buy will be a Stila, closely followed by more Inglot...
Conclusion: for MAC eyeshadows these more than do the job. A little pricey at £11.50 here in the UK but will last me years!

First off - they need to reduce the price. €15 for an empty palette is a bit steep. I just filled my first palette but i'm a bit OCD of having loads of empty spots in my new one.
I use a tweezer when I have to remove a shadow, the cutouts aren't really handy for that. The shadows aren't really tight either, they have some space to wiggle around. So don't drop it!
It's a sleek palette, it looks nice & luxe. continued >>

I have nothing but AMAZING things to say about this palette. De-potting my eye shadows was a great decision. This makes me feel confident that they wont be damaged when traveling and it looks very sleek. There is nothing like looking at all your beautiful MAC shadows arranged in a palette :]

I finally finished filling my 15 pan palette (with Paradisco - a new favorite) and I must say I love to just sit back and look at all the gorgeous colours! I'm glad I bought this palette and would recommend it to anyone. Only one colour mistake (Cranberry looks hideous on me), which I think are pretty good odds considering the shades were all purchased online. My only con is that it gets so dirty. A makeup wipe does a great job of cleaning and it's back to being as good as new! I would definitely repurchase...but I'm hoping that this will be enough eye shadows to last me for awhile. ;-)

I love this palette, I finally got my first one last week. It makes using eyeshadow so much easier. It is a bit expensive, but I love how small and sleek it is. I have Vanilla, Jest, All that glitters, Expensive Pink, Retrospeck, Patina, Woodwinked, Honey Lust, Amberlights, Satin Taupe, Sable, Bronze, Knight Divine, Club, Magnetic Fields

This palette is great if you pop out the 15 pan plastic insert out of it. You can put a lot more pans of various shapes and sizes that way. It's all black and looks pretty good. It makes a great palette to keep at home/storage. With that said, I would never take this traveling because it's a bit on the flimsy side as far as traveling goes. However, if you're just keeping this on the vanity it's fine.
I took a lippie off because it would be great if it had a clear top so you can see your colors. Also, while it's not terribly expensive, it probably costs them 20 cents each to make one, so part of the one lippie off is for the crazy retail markup on this. I would buy this again when I run out of room on my other 2 palettes, but I don't think I'd travel with it.

Love these! They make eyeshadow storage a breeze. WILL REPURCHASE!

I seriously love this thing. It just makes having MAC shadows so much easier. It is just so much easier to have them all in one place rather than in individual pots. If you are able to get your hands on one of these, I would recommend getting one. You can also take the insert out which allows for more shadows to be placed. I currently use this for my MAC shadows & a Zpalette for my others. I really cannot complain about this palette, but I do like my Zpalette more. continued >>

I only have one at the moment, but looking forward to getting my next one as I've almost filled up my first one. The palette is nice and slim and I haven't had any troubles with it so far. I don't mind there not being a mirror as it looks more professional without one in my opinion though I wish it had more than 15 slots which I know you can take the insert out, but I think it looks less organised. I also wish the magnets were in the palette like the Stila ones rather than on the eyeshadow pans.
Overall, it does what it's suppose to do and I shall keep purchasing them, I just have some personal preferences.

I love my MAC 15-pans. I've filled up 3, and have enough shadows for a 4th one, which I need to pick up ASAP. With so many shadows, the only solution is 15-pans. At first I was hesitant, thinking they would be too large and cumbersome to use on a daily basis, but I've become a pro at handling them (pardon the pun). They're super sleek and thin, which is a very important consideration for me. I don't mind that they don't have a mirror - when I travel I swap a few shades into quads. The only issue is that you can't see the shades inside - I've solved this by putting a tiny sticker on each one, in the colour of the shadows inside. this makes it a breeze to find the palette I want, and they're all there, easy to find and easy to use. I can't live without my pro palettes! And don't forget about all the B2M's from depotting the shadows :) Just remember, the bottom of the palette is metal, so you will need magnets on the shadow pans. This is opposite of some others, such as Stila, where the palette is magnetic and the pans are metal.

I love this palette, I love having all my shadows togethere so i dont have to be searching through my stash each time i need a certain shadow. I subtracted 2 lippies. 1 for not having a mirror, which i think it would be easier and more convinient for it to have a mirror for travel, and the second lippie for how it doesnt open up ill the way, i wish it did because i already know im gonna end up breaking it one day. Though im not completely satisfied, i will buy this again only because its a better choice than having to waste 5 minutes looking for a eyeshadow.

I love having a palette, before I owned one I would always stick to the same colours as it's so fiddly opening and closing all the different eyeshadow pots. I love being able to see so many colours at once, it makes it easy to put colour combinations together. I have taken out the 15 space insert part as I had more than 15 shadows and wanted them all to fit in. The shadows all stay in perfectly ok. I reckon you could get about 24/25 shadows in there which is obviously more space saving than buying another palette. I would definitely recommend depotting your current eyeshadows and putting them in your palette, I looked on YT first to find out how to do so and its actuallly really easy. Then you can back to mac your old pots and get some new lipsticks! (My MAC counter accepts eyeshadow pots with no pans.) if you are thinking of getting one I would 100% recommend that you do, makes life a lot easier in the morning. Just be careful not to drop it! Xxx

The MAC 15 Pan palatte keep my eyeshadows organized and customized for my use. It is also a great way to get rid of clutter which tends to happen if you have lots of eyeshadows in single pots. I also like that I can see all the beautiful colors whenever I open my palatte. With the single pots, I tend to forget that I have this or that color. I keep my palattes clean and tidy at all times to better appreciate the eyeshadows. I just wish that the palatte itself is magnetic since the small round sticker magnets are not available where I live.

Overall: 4 Price: 4 Packaging Quality: 2 Buy Again? Yes. When you buy MAC shadows in tha pan form, it costs $11US as opposed to $15 for tha individual pot. Tha pallete itself costs $14 or $15 I believe. My first one seperated because tha hinge broke & tha latch broke aswell which is very disappointing. I also think it should come with a mirror. I think I will glue one on myself. Despite it's flaws, I will be a user because I like my shadows in a pallette & it saves you some paper in tha long run. I also love that MAC doesn't animal test... continued >>

these are extremely nice and sturdy. whether you put mac in them or not all of the mac empty palettes are a must have. mac (estee lauder) does not test on animals.

Love love LOVE this! so easy for carrying around MAC eyeshadows. Wish it were a little more universal, but if you love your MAC shadows, it is streamlined, strong, light and easy to carry around. A million times better than carrying around the shadows seperately. Reasonably priced, a must-have item for makeup artists
