Adjustable lower back support belt made with mesh and elastic fabric. Thank you for viewing. Cute red accents on a black base ♡ Can be used for lower back pain and cold prevention. I use the same product in size M, and the mesh feels breathable in the summer. The material is firm, so it doesn't feel scratchy if you wear something underneath. The Velcro is strong (゜o゜;) It makes a loud ripping sound when attaching and detaching, so it's for those who are okay with that... In the fall and winter, it provides warmth and helps prevent chills. Although it's for the lower back, if there's enough room in the size, it can also be wrapped around the pelvis. There is no size tag originally, but it is size L. This size L has only been tried on once and is selected as new and unused. Thank you very much (⁠.⁠ ❛⁠ ᴗ⁠ ❛⁠.⁠)
