Gelatin sheets (or "gelatin leaves") are a specialized product that's used by bakers in jellied dishes (usually melted) and for fine decorating details like butterfly wings and other translucent decorations. Works like granular gelatin found in your local grocery store, but in a different form. Rather than a powder, it is takes the shape of thin sheets or leaves of gelatin film. The sheets dissolve more slowly than the granulated form, but also produce a clearer gelled product.
