I run a creative workshop in Tokyo called 「もくもくはりねずみ（Mokuhari）」, where people can freely make things using woodworking tools, 3D printers, and laser cutters. I wanted a safe and simple way to display event posters on pegboards. We used metal hooks before, but since many young children visit our space, I designed flat corner clips that are safer and hold posters securely on 25mm-pitch pegboards. I hope they’re useful in your workshop or store!
