This is a stainless steel bottle that was a novelty item given away by Uniqlo in January 2018 to customers who spent over 10,000 yen! The color is black (matte). I just opened it for the first time to take photos. It is new and unused. The instruction manual is included. Although it is new, the red outer box has some minor scratches due to being stored at home. I would like to sell it to someone who doesn't mind. Size: Approximately 8cm in diameter, 13cm in height Capacity: 0.28L Heat retention: 46 degrees Celsius or higher (6 hours) Dishwasher safe: No
