Big Kid BOSS UNIVERSAL Blocks

Big Kid BOSS Universal Blocks are 1/4” thick polycarbonate blocks available in the following lengths: 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 blocks. The Universal blocks have large sphere handles for a comfortable grip. They are "Universal" because they have such a great mixture of rigidity and slight flex for most applications. All blocks are 2.687" wide. Available "Standard" for sticky back sandpaper and with "Hookit Backing" for velcro sandpaper.
