I used this when I was suffering from lower back pain during my pregnancy. In my personal experience, it helped me a lot. I'm selling this in the hopes that it will provide some relief to pregnant women experiencing similar minor troubles. Tokotchan Belt, size M, total length 145cm (self-measured) Please understand that the total length and the measurements in the third photo are self-measured. There is some dirt on the Velcro (see photo 4). Since there is no box, I will put it in a plastic bag and ship it via Mercari delivery. Please purchase with the above in mind. Thank you for looking.
