I love the Witches Night stamp set. It's clear photopolymer, which keeps the price down, but it stamps very crisply and clearly. And the design is so intricate, it does all the work for you; there's no need to embellish any further once you've stamped it, if you don't want to.
The box dimensions are about 2"x2"x2", so it's perfect for little sweet treats. And the box flaps curl over and it seals itself over the teeny tiny handle. How sweet!
You can buy any of the items I used from my Stampin' Up! shop.
