Flat wire staples, type 51, are the universal stapling solution for numerous applications when fastening thin materials. They are specifically designed for thin materials where the staple leg should not penetrate into the material being stapled. The narrow leg allows the staples to be driven deep into the material, ensuring a secure fit and a discreet back. These flat wire staples are compatible with staplers from the brands Bukama and Rocagraf, making them ideal for both professional and DIY users working with thin cardboard, films, labels, papers, and more.
