This is a MALLOW knit balance ball from &MEDICAL, in black. It has only been used a few times and has been kept in the corner of a room. There's hardly any sign of use, and it's in beautiful condition, but the bottom might be a concern for some. Please refer to the photos. Retail price is 22,000 yen. The box is not included, and I will look for the instruction manual. I will upload a photo of it as soon as I find it and send it with the product. It will be shipped deflated. Please be aware of this. This stylishly designed balance ball is perfect for use in the office or at home. - Color: Black - Design Award: Good Design Award 2022 - Usage: Seated use in the office or at home - Size: Balance ball type - Features: Stylish design
