This is a plastic water bottle from STAN S P O R T. It's green (1000ml) and orange (500ml). I think I used them a couple of times when I bought them. After that, they've been stored away. Since I don't plan to use them in the future, I'd be happy if someone else could. They've been stored for a long time, so please wash them before use. Please be aware that there are scratches and minor imperfections. I may have overlooked something. Please forgive me. Please check the images. Please refrain from purchasing if you are nervous or concerned about minor details. We do not accept claims, so thank you for your understanding.
