This is a non-sale stainless steel bottle from Anytime Fitness. It's a limited item for gym users. There are some minor scratches from use, but no noticeable damage or rust, and it's still perfectly usable. The inside is also relatively clean. It's recommended for everyday use, as well as for the gym, training, and outdoor activities. It's a non-sale item, so it's difficult to obtain. Instant purchase is welcome, first come, first served.
