Mudtools Green Rib #0
MUDTOOLS RIBS are made from flexble material that is considered the "stainless steel" of plastics. Unlike rubber, this material will not develop burrs of cracks. In fact these ribs will burnish themselves as you use them, so, the more you use them the nicer them become.
The green rib is of medium flexability, great for compressing bottoms, burnishing, trim marks, throwing and handbuilding.
