This is a brand new item that has never been used. Free shipping within Japan. No comments needed, immediate purchase OK. The price is already at its limit, so I don't offer discounts except for occasional sales. However, I'm open to price reductions for multiple purchases, so feel free to comment. This is a must-have item for those who often lose their "earring backs." These are double-lock earring backs that wrap a metal back in silicone, making them less likely to fall off. They are made of 18k gold, which is less likely to cause metal allergies. This is a must-have item for the beach or pool, where lost earrings are impossible to find. They can also be used for cartilage earrings. Recommended as a replacement for lost earring backs or as spares. ◇Size◇ Diameter: 5mm ◇Quantity◇ (Please specify quantity) ◇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.
