PROTOLINA®
Sulfur-free proto typing modeling material, designed to replace Kleen Klay and Roma Plastalina. For model making, sculpting, mold construction and work requiring non-hardening, reusable, self-adhering ultra smooth clay. Unlike the materials it replaces, Protolina contains no sulfur or sulfates making it ideal for use with silicon type mold compounds. Protolina is available in three firmnesses and two colors.

NOTE: The 1 lb, 1 x 3 x 5 5/8” bar design deep scores the 1 lb. bar into 3 pieces. These pieces break off easily and fit the Gruber clay extruder.
