Thank you for viewing! Iki-iki Lab KARADA Factory Karada Factory Recommended by a chiropractor Back Supporter Size M Back straight! Adjustable cross belt for back support. Easy to put on, secure hold, comfortable support without strain. Please check the images for size and material details. I bought this for my child at Shimamura, but the size was too big, so I'm selling it. I only tried it on once at home over a T-shirt, but please refrain from purchasing if you are a perfectionist or overly concerned about minor details. I threw away the box. Please consider this only if you understand. Thank you.
