This is a brand new item that has never been used. Free shipping within Japan. No comments needed, immediate purchase OK.

This is a must-have item for those who often lose their earring backs. These are "earring backs" made with a double-lock design that encases the metal back in silicone, making them difficult to lose, and using 18k gold to reduce the chance of metal allergies. This is a must-have item for the beach or pool, where lost earrings are impossible to find. Can also be used for cartilage earring backs. Recommended as a spare earring back in case of loss. ◇Size◇ 5mm diameter ◇Quantity◇ 1 piece ◇Color◇ k18 Gold ◆Important: Please Read◆ To reduce the burden on postal workers, there will be no shipping on weekends, holidays, or the following day.
