Opened for photography purposes for listing, but unused. This is a warming product that uses a dedicated heating sheet (disposable heat pack) inserted into an A4-size urethane cushion. The expiration date has passed, so please consider the dedicated heating sheet (disposable heat pack) as a bonus. For subsequent uses, please use your own disposable heat packs. The cushion can be hand-washed. The outer box has traces of price sticker removal, dirt, and crushing.
