Link Lock (5 pieces)
925 solid sterling silver Link Lock (5 pieces)
Link Locks are an Australian invention that allow charms to be securely fitted to a charm bracelet without the need for a visit to the jeweller.
They are around 5.5mm long, so a little smaller than most jump rings. They may not suit larger links in heavier charm bracelets as they are quite small.
To fit link locks it is best to have good eye sight and the help of a magnifying glass or better yet, a pair of +3 reading glasses so you can work hands free.
