Coin Ring Size 20, Mexico 5 Pesos Coin ring made using a real Mexico 5 Peso coin. Size: Approximately size 20 (This is the size at the narrowest point). Width: Slightly over 4mm Weight: 3.8g The design of the Aztec calendar stone looks great when made into a coin ring. Sample coin not included. ⚠️ The coin ring has been coated with an accessory-grade fluorine coating agent to slightly alleviate discoloration and metal allergy reactions, but this is temporary. Please refrain from using if you have a metal allergy. Although listed as new and unused, the coins used were originally in circulation. There may be some scratches, distortions, and dirt, so please judge from the images. I am committed to making transactions pleasant. Please feel free to comment if you have any questions.
