This is a warming coaster for placing warm cups, etc. You can enjoy warm drinks while keeping them warm. How about one for your workplace or home? It's not new, but the condition is relatively good. Thermo-Matic Heating Coaster Size: Approximately 12cm in diameter Heating area diameter: Approximately 8cm, stainless steel Height: Approximately 2.8cm Cord: Approximately 57cm, USB terminal power supply, non-removable. It heats up immediately when the terminal is plugged in. ●●It's not very visible, and even looking at it, it's not very noticeable, but you can tell that the metal plate and edges are not the same as new. The outer box is clearly old. ●Everything in the images is included. (There is no instruction manual, but I don't think you'll have trouble operating it.) ●It is intended to keep warm items warm, and is not a cooking heater. ●Please be careful with the terminal. It is not powered by a wall outlet. ●The box will be folded due to its thickness, and will be waterproofed and cushioned along with the main unit for shipping. It may be sent via Rakuraku Mercari. Please let me know if this is inconvenient for you. ●I have also listed another unused one. Since it is slightly thinner, I also accept combined purchases. (Please forgive me if it is sold out.) Although it is old and the function is simple, if you only look at the preheating time and temperature, it may be more powerful than newer ones. Thank you for looking.
