Set of base metal magnetic clasps, great for people who have trouble doing up bracelets or necklaces. Available in bright silver, bright gold or black. Total length of clasp (including parts): 12mm, width: 6mm. To attach to a bracelet or necklace, simply thread a head pin through one side of the clasp, so that the 'head' sits against the larger hole. Leaving a gap of 10mm, cut off the excess head pin. Twirl a loop. Repeat with the other side, then use these loops to join your clasp to your project. Please consult your doctor before using magnetic beads or clasps if you use a pacemaker or other electrical medical devices.
