Flat wire staples, type 51, are the universal fastening solution for various applications involving thin materials. They are specifically designed for thin materials where the staple's crown should not penetrate into the material being stapled. The narrow crown allows the staples to be driven deep into the material, ensuring a secure fit and a discreet appearance. These flat wire staples are compatible with staplers from the brands Bukama and Rocagraf, making them ideal for DIY enthusiasts and professionals working with thin cardboard, films, labels, papers, and more.
