Thank you for viewing. I purchased this at an electronics retailer, but I am selling it because I bought another one. I opened it and spread it out, but I did not use it and stored it in the box, so I think it is in a clean condition. Operation has been confirmed. This 1.5-tatami mat electric carpet provides comfortable warmth with a power consumption of 330W. - Brand: Panasonic - Model Name: DC-2nk - Type: Electric Carpet - Power Consumption: 490w - Size: 2 tatami mats - Heater Size: 176 cm x 176 cm Thank you for viewing. Please note that the item will be shipped with the shipping label directly on the outer box. Please purchase only if you understand that this is a used item and that it has been inspected by a non-professional.
