This is a face band for compression after liposuction from Shonan Beauty Clinic. I purchased it on Mercari, but since it wasn't for the cheeks, I am selling it without using it myself. The previous user stated they used it for less than a day. It seems to be for the area under the chin, the face line, and buccal fat. Those who have cheek liposuction cannot use it (confirmed by a doctor). Free size. It has been home-cleaned and is in a clean condition. Retail price: 6050 yen.
