Thank you for viewing! ◎ This is a set of two Yutapon rubber keychains! ⭐︎ Sumikko Gurashi Neko Relax Yutapon I used this for display, so I have never warmed it up and used it. * Product Description Simply heat it in the microwave, and the comfortable warmth lasts for about 30 minutes. The generous steam from the azuki beans and ceramic gently warms your hands, etc., and helps you relax. It can be used repeatedly for 365 times. ⭐︎ Sumikko Gurashi ~ Kirakira Bath Time ~ Neko design rubber keychain from Ichiban Kuji I also used this for display, so I have not used it. I think there are no stains. Please purchase if you understand that this is stored by a private individual. I will strive for polite and prompt service ☺︎
