This is a must-have item for people who often lose their "earring backs". These are "earring backs" that use a double-lock system, wrapping the metal back in silicone to prevent them from falling off, and are made of 18k material that is less likely to cause metal allergies. This is a must-have item for the sea and pool, where you can't find 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◇ (Please specify quantity) ◇Color◇ k18 Gold ◆Important: Please Read◆ To reduce the burden on postal workers, there is no shipping on Saturdays, Sundays, and holidays, nor next-day delivery.
