Kidney Polymer Rib

The traditional kidney-shape of these potters ribs is the most universally recognized clay tool.

All Mudtools polymer pottery ribs are made of a unique flexible material that will not develop burrs or cracks under normal use. We’ve found that over time the rib becomes even more polished. Each polymer shape is available in a variety of hardness.

Red = Very Soft, Yellow = Soft, Green = Medium, Blue = Firm
