Pro Sponge (Porcelain) by Xiem Tools is specifically designed for use with porcelain bodies.
It is an extremely soft, super absorbent and long-lasting chamois sponge and the tapered edges give fine control.
There is also a Pro Sponge (Stoneware) available for working with stoneware bodies, and a Pro Sponge (Finishing) available for clean finishing work.
Note: These sponges are sold individually
