I admire fancy nail art, but I can barely manage to make my nails look nice with a solid color. Luckily, I have other options. ThinkGeek offers press-on stickers in Batgirl and Wonder Woman designs. All you have to do is peel, stick, and trim off the excess with an emery board (included in the kit). They last for about a week, even longer if you use a clear top coat. They’re easy to remove, too; they just come off with nail polish remover.
