We just received in some metal magnetic clasps.
The magnetic locking clasp is perfect for 1 strand of paracord to fit into it. Simply cut the paracord and secure it into the clasp with super glue. It's great for making single strand bracelets. The neodymium magnets are super strong and the rotating lock helps it stay secure to your wrist.
