This is a size LL back support belt I had made at a hospital a long time ago. I've kept it ever since, but I'm selling it because I don't use it anymore. I have a 90cm waist, and it fits me without any problems. Also, the back part is mesh, so I think it reduces stuffiness. Before shipping, I will wash it by hand to remove any dirt. It's still usable, so how about it if you're suffering from back pain? Thank you.
