Big Kid BOSS Blocks – UNIVERSAL KIT

Big Kid BOSS Blocks Universal Kit has three 1/4 thick polycarbonate blocks (24, 18, & 11). Polycarbonate is a much stronger material so if you are hard on your tools or have butter fingers, we’d recommend our polycarbonate BOSS blocks over our acrylic block kits.The Universal blocks have large sphere handles for a comfortable grip. They are our Universal kit because they have such a great mixture of rigidity and slight flex for most applications.

All blocks are2.687″ wide.

Available “Standard” for sticky back sandpaper and with “Hookit Backing” for velcro sandpaper.
