What a whopper. This textured rolling pin, designed by Green Stuff World is 12.75 inches (32cm) long by 1.25 inches in diameter (3cm). For massive terrain patterns, can be used on Green Stuff, epoxy putties, Sculpey, Fimo or salt dough. Made from a special non-stick material, clear PMMA, the possibilities are endless. For decent instructions on how to use it, check out our blurb on the Assembly Guides page.
