I used this for a week during the downtime after liposuction! I bought several because I was hesitant to use the same one for a long time, but I only used each one once or twice. They are all size M, which is the most standard size, so I think most people can wear them. I bought them on Amazon, so I've also included a photo of my purchase history! ※Please feel free to ask any questions in the comments. ★I want to sell these, so please comment with your desired price (*.ˬ.)
