This tool helps when opening 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. There is a dedicated non-slip grip to hold the bottle more easily while using the wrench to turn the cap.
