I used it for a total of a few hours in the living room for about 3 days after purchase, but it didn't fit my body, so I'm selling it. I didn't use the belt either, so the rubber hasn't stretched much. Since it was only used for a few hours, there are no pills, but please understand that it is a used item before purchasing. ※I will conduct transactions sincerely according to Mercari's official rules. Cancellation due to personal reasons after purchase is a violation of the rules.
