This is an item that is a must-have for people who often lose their earring backs. These are "earring backs" that use a double-lock system where the metal back is wrapped in silicone, making them hard to lose, and are made of 18k gold, which is less likely to cause metal allergies. This is a must-have item for the sea and pool, where you can completely lose them if they fall off. Can also be used for cartilage earring backs. Recommended as a spare for earring backs 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 Saturdays, Sundays, and holidays, or the next day.
