Flat Glue-On Bails (Package of 2 bails)
These are useful when you have a loose cabachon and want to attach it to a hanging bail for your necklace. Two sizes: small (bail about 11mm, overall about 16mm, hole about 2¾x3½mm) and large (bail about 16mm, overall about 25mm, hole about 5x7½mm).
A good super glue or E6000 (glue, tape together until dry) will provide a sturdy attachment.
