BPA-free stainless steel water bottle, 0.35L model with excellent heat and cold retention. The gasket is integrated, making it easy to wash. I bought it about a year ago. Used about 5 or 6 times. It's very clean. I am selling this one while it's still in good condition because I bought a different color. *Includes box and instruction manual* - Brand: TIGER - Color: Off-white - Capacity: 0.35L - Material: Stainless steel - Features: BPA-free - Heat retention: Keeps warm for 6 hours (67°C or higher) - Cold retention: Keeps cold for 6 hours (8°C or lower) MMZ-W351
