【Unused】 Toyo Case Push ECO Hand Warmer This eco-friendly hand warmer warms up when you click it and can be reused by returning it to hot water. I received it as a prize, but I am selling it because I don't use it. ⚠ Although it is unopened and unused, there is a small black stain on the cover of the product itself (see image 5). The outer box also has minor scratches due to home storage. Please consider this before purchasing. Instant purchase without comment is OK! ・Size Hand warmer: Approx. W10 x D1.5 x H8cm Cover: Approx.
