BOI Dokutech Filing Fastener SM-3, 100 Pieces, Silver Metal

Loose documents that need to stay together in a file often slip out of folders or get lost. The BOI Dokutech Filing Fastener SM-3 solves this by securely binding punched papers into a file or folder.

The galvanized steel resists rust and can be reused many times, making it a reliable choice for offices, schools, and home filing.

Tips

For best results, use a standard 2-hole punch to prepare your documents. Insert the prongs from the back of the file, then fold them flat against the top sheet. To remove, gently straighten the prongs and pull the fastener out. Store unused fasteners in their original box to keep them clean and tangle-free.
