Sadly, I'm totally not in love with this mascara. It takes a lot of hassle to apply it properly. If you can spare the time in the early morning when you're rushing to work, definitely give this a shot.
The brush is exactly like it shown on the packaging - just check the pic uploaded by the other reviewer. I noticed that I can apply the mascara using the short bristle side lightly only, ie. I cannot apply with that side to all my lashes as this means way too much mascara and it will become super clumpy. For a easier use, I actually use the longer bristle side only. The difference here is the latter method will not give you thick lashes. Btw, I have also added a photo showing the instructions of use at the back of the packaging.
This mascara gives volume and length - decent but not the best. You can try building up the mascara if you don't mind the fuss in combing the clumped lashes. They are rather difficult to separate despite the use of metal lash comb. Honestly, I'm very used to combing my lashes, so you can imagine how much hassle it takes for me in order to type this comment. Curl holding is decent, but definitely not as good as the Length & Curl/ Volume & Curl mascaras.
Overall, a nice mascara if you don't mind the hassle in clumping and combing. Otherwise it's just an average mascara that I will finish and will not repurchase.
