Inspired by the shape of the traditional tailor's chalk, ArtGraf Tailor Shape is a block of pressed pigment, designed for drawing and painting. They are soft, water-soluble, easily mixed either in dry or wet applications. Draw on canvas or paper, layer to mix, activate with water at will. Or you can use like any ol' water color with dry or wet techniques. Produces a wide range of light, dark, and opaque colors. Amazingly versatile tool. Al isn't sure how he lived without these. Made by Vicaro, Portugal's only pencil company. Family owned since 1907.
