If you don't need the box, it's ¥200 off. This is a very rare, not-for-sale item. I obtained it a few years ago through a point exchange at a Hong Kong convenience store. The material is mesh, so it's lightweight and I think it's especially convenient for outdoor activities or at the pool in summer. Please take a look at the photos for more details. I've never used it and have stored it in a drawer. The outer box is crushed, but the contents are clean. I have two of the same item. If you purchase them together, I'll discount the shipping cost. Please leave a comment before purchasing. If you're interested, please consider it.
