This is a yoga mat case sold by Lava. I received this from someone, but I've decided not to use the case. It has never been used. - The following is a quote - A stylish design, now available in a nylon material version. It's even lighter and easier to use. The wide zipper opening makes it easy to put your yoga mat in and out, and it still has a convenient pocket that can hold a SUKALA x SIGG original 1-liter bottle. It also has excellent functionality with quick-drying, antibacterial, and deodorizing properties. The length of the strap is adjustable, so you can use it as a crossbody bag. This is a convenient mat bag that allows you to go to yoga with just this one bag. Size (cm) Height: 69.5 Depth: 17 Circumference: 53 Strap: Max 84 Retail price: 5500 yen
