Sorry, this item sold. You may also like:
15mm x 15mm (about 5/8 inch). Hole is about 2mm wide.
Very flat (about 1mm), but very strong and durable - I tried, and couldn't bend these.
Identical on both sides.
These are made of Tibetan silver, which is a lightweight, lead-free, silver-tone alloy.
If you'd like this in a different quantity, just send me a message - I'm happy to work with you.
