These atomizers are the best!!!!!! They hold a lot and are refillable. Got my first one on Ebay, but when I needed another, I got one that comes with a funnel and travel bag at packingperfume.com for the same price I had paid for just an atomizer. Now I have many!!! I fill these with all my favorite senses so I don't get them mixed up!!! packingperfume.com also had all kinds of rollon bottles, which are perfect for my heavier perfumes like opium, the one and obsession and prevents me from overspraying, which can be a disaster! The hard part is making sure my friends don't keep them. When we go out, everyone knows I always have them in my back pocket or purse. I HIGHLY RECOMMEND THESE BOTTLES!!!! GREAT GIFT IDEA!!!!
