This tool helps when opening tough bottle caps clogged with paint. This opener set is for opening the caps on paint made by GSI Creos. The flat shaped spectacle wrench has a socket for “Mr. Color GX use” and “Water based hobby color use” on either end, and one for “Mr. Color use” is molded into the rear side.
