Thank you for viewing. ※ Only One Air Cushion - Enza DX Please use this for hemorrhoids, bedsores for bedridden patients, and to alleviate pain after childbirth. Enza 13DX, outer diameter 33cm, inner diameter 10cm I purchased this at the hospital, but I was able to sit without using it, so it is unused. There are some areas where the towel fabric has slightly changed color due to storage. The Enza is made of rubber and has a valve. Please inflate it with air and adjust it to your preferred thickness and softness. I will fold only the contents and the explanation part of the box and ship it in a smaller size, so please understand. Retail price: 4290 yen
