Barrel Clasps - at this price, use them with the kids too! (save 50%)
$2.00 On sale
These screw or barrel clasps measure 13mm long (including loops) x 3mm wide. The loops on the end can be opened up to attach to your jewellery pieces. The loops 'swivel' as the clasp is done up, so your item won't twist.
These are probably one of the oldest style of clasps, but they are still a good'n, and at this price, buy some for the kids' kits as well. They can easily string up beads on fishing line in the holidays for hours of fun :-)
Silver and Gold available, in packs of 10 clasps.
