I recently bought several styles of the new (to the U.S.) Essence Studio Nails Nail Fashion Stickers. I'm pretty much a sucker (and a psycho) for anything Essence. I tried them out this past weekend but did not have luck in the end. Here is a quick picture I took.
I tried to think of a way to shift it or cut pieces off of other stickers and make it work somehow, but eventually came to the realization that it just wasn't going to work for me. The kind ladies on MUA suggested that I could use them still and just paint my thumb nails black. That's a great idea, actually! I may end up doing that if I decide to keep the other packs I bought. It kind of defeats the purpose of not having to paint your nails and wait for them to dry and all that stuff, though. :(
If you have wee little nails, or just don't have big man hands like I do, these could work for you. I've also gathered that they do not stay on very long - so it would probably be a one shot day long kind of deal. Still fun and cute and cheap.
