Lightweight hook and eye with adjustable chain clasp.
Note, the bar that the loop for the single strand is a attached to is a solid bar, not a hollow one. I spent quite some time puzzling that out.
Most appropriate as a clasp for a necklace.
Semi-matte finish.
The hook is 18mm long, the chain is 4mm wide. 70mm is the overall length.
70mm By the each.
