USB cup warmer purchased at Daiso. I'm selling it because I don't have a chance to use it. Although it hasn't been used, I turned it on once to check the operation. Therefore, it is listed as "Like new". - USB powered cup warmer, easy to use - Keeps hot drinks warm slowly - Convenient for desk work and telework - Simple white design - Model name: Cup Warmer - Color: White - Power supply: USB connection - Function: Heat retention
