Shape 5 Polymer Ribs are Mudtools' larger version of size 0 and 1 Polymer Ribs. These traditionally shaped kidney ribs are useful for sculpting, handbuilding, and throwing. Blue Mudribs are the firmest color of the polymer Mudrib collection.
All of the Mudtools polymer pottery ribs are made of a unique flexible material that will not develop burrs or cracks under normal use. Over time the rib becomes even more polished. Each polymer shape is available in a variety of hardness:
Red: very soft
Mudrib shape 5 is 4.13" long and 2" wide.
