This is one boot used for treating a horse's hooves. I've had it for about a year, stored at home. It came in a box without any plastic wrapping when I bought it, so I've stored it as is. The zipper opens and closes without any problems. There are stains that appear to be from adhesive from when I bought it (see photo 6). *Effective for treating thrush, canker, and bruised soles, etc. Since it can get stuffy inside, you can put a baby diaper in it to prevent this. ■Size (widest part of the sole) 7 (140-148mm) ■Color Blue ■Retail Price 11,000 - 15,000 yen Here is a detailed description of the product on this site: Woof Wear Medical Hoof Boot https://share.google/MF1PnhnOlP7rzvixr
