These items are like new, purchased for ￥5,980 for two. They were only used for about 3 hours. Here's why I'm selling them. I sleep on a very firm mattress, and the pressure on my heels caused pain and calluses. I bought these products to protect my heels while sleeping. The cushioning was great, and the pain disappeared, but they were bulky. While sleeping (especially in winter), they combined with the futon and woke me up. Although I was using them for a slightly different purpose than preventing bedsores, I felt they didn't suit my sleep, so I'm selling them. The size is approximately 22.5cm for the height of the sole, 22.5cm from the heel to the Achilles tendon, and 11cm for the width of the foot. I've included the URL of the product I purchased: https://item.rakuten.co.jp/eightyoneshop/lg01zrq3153/ Please refer to it for details with images. * Shipping will be via Rakuraku Mercari Delivery, Takkyubin 80 size. * Please note that I am not accepting price negotiations. * If you have any questions other than those in the description, please ask.
