Thank you for viewing! These are charms made with resin. As they are handmade, please understand that there may be small air bubbles. They were originally planned to be sold at a charity bazaar, but the event was cancelled. They have been stored at home since then (made in the summer). I am selling them as a set, so how about giving them as gifts to your cat-loving friends? The backs have sparkling holograms. Shipping will be via postal mail. Thank you. #cat #catcharm ※I am not accepting custom orders. I apologize for any inconvenience.
