This is a size L Toko-chan Belt 2. I planned to use it after giving birth, but being a lazy person, I only used it a few times and stopped wearing it. It has been used a few times, but please understand that it is not new and is a used item. Upon inspection, I noticed a slight distortion as shown in the fourth photo, which I didn't notice when I used it a few times. Here's the description from the website: This pelvic belt can be used for a long time, from pregnancy to postpartum. It's easy to put on and comfortably supports the pelvis. It helps to reduce the burden on the lower back.
