Water traces
They are a type of stickers in which the impression is done on a paper that has two sheets, as well as the sticker, but in this case it must be introduced into the water for about 15 seconds. When doing this, the base, colorless, from a fine transparent paper film that has the impression is separated. It applies to the surface of the miniature and a dry paper is passed (a disposable handkerchief is the most common), and the decal adheres adheres adopting the shapes of the base surface. It is a type of decal mostly used in miniatures to paint and assemble, and almost not used in Die-Bast models, since it requires a manual application.
