Convex Ring Blanks - Wide (12.5mm) - Lightweight and durable base for polymer clay rings

These convex ring blanks are baking bases designed to be covered with polymer clay and baked together with it. They create a strong internal base that gives the finished ring its shape and durability. The blanks feature a convex, wide band measuring 12.5 mm (1/2").

The convex base has a clearly rounded top, giving the finished ring a smooth, domed curve. The wide band gives you more surface to show off the clay design. It is ideal for working with colored polymer clay veneers, slices of canes, or crisp border texture impressions sized to fit the ring width. Each lightweight blank holds its shape perfectly during baking without warping or collapsing. The base is intended to remain inside the finished piece.
