Hakugen Earth Range de Yutapon Warm and comfortable sleep! Ready to use after microwaving! Warmth lasts for 7 hours. Reusable. This is an unused item, but it has been stored at home. I purchased it two years ago. I opened the package to check the contents, and the tape didn't come off cleanly... If you don't mind, please purchase. I will fold the box and ship it via Yu-Packet Post. Immediate purchase and silent transactions are welcome! ⭐
