Decorating rib sets are the ultimate clay decorating tools. Each set contains four different ribs, with three different patterns on each. Use to create texture on any malleable surface, including clay, thick slip, underglaze, engobe, icing, thick paint, gel mediums, glue, plaster, and putty. Simply drag the patterned edges across ceramics, glass, canvas, walls and even cakes adding three-dimensional details. The designs can be pulled in straight, wavy, or crisscross patterns to create beautiful custom designs. The Flex Soft ribs have a more pliable consistency for use on the pottery wheel. To clean, simply wash with soap and water, then blot dry. Xiem or equal.
