Do you cut glass? These friction buttons are super handy little helpers. The pack comes with 16 buttons, and their job is simple: they keep your glass from slipping and sliding while you're cutting on a grid work surface. You press them onto the grid, and they hold the glass firmly in place – even when you're cutting strips or circles. They're ideal to use with tools like 'The Cutter's Mate' (#5112) and its attachments. If you've ever struggled with glass moving around mid-cut, these buttons can make your life a lot easier. They're small, reusable, and just one of those simple tools that improve precision and safety. Great for hobbyists, crafters, or anyone working with glass in a workshop. No complicated instructions – just stick 'em on and cut with confidence.
