I used this about twice over my clothes for lower back pain, and it's in very good condition. It's a size L, but it feels like a regular M size in terms of fit. It provides a very firm hold. I haven't used it much, but please be aware of minor linting or slight creasing. Lumbar support corset Vantelin Retail price: 7700 yen Price reduction: ❌ (Not negotiable)
