The Artis Decor Double Ball Tool (901000203) is a double-ended ball tool, with diameters of 2.4mm and 2.8mm, one at each end of the handle. The ball tips allow you to mark, shape and emboss soft materials such as modeling clay, fondant, cold porcelain or paper, and are also widely used in engraving, parchment craft and quilling. The handle facilitates control of the movement even in small and repetitive details, and the two tips of different sizes allow you to work on details of different scales without changing tools. It is a useful accessory for those who do modeling, embossing scrapbooking, handmade cake decorating or other detailed craft work.
