Purchased on Rakuten in late November for 6980 yen. I set it up, but my dog never went inside it (*ToT), so I'm selling it. It's almost new, but please refrain from purchasing if you are concerned about minor scratches. Warm and cozy kotatsu, for pets, 20W - Size: Width 45 x Length 33 x Height 30cm - Power: 20W - Materials: ABS resin, polyester - AC adapter: 100-240V/50/60Hz 12V 2A - Temperature setting: Overheating prevention with a thermal fuse My impression after setting it up is that it's for pets and provides a gentle warmth. It's different from a "kotatsu" for humans. Please understand and agree before purchasing. Will be shipped in simple packaging. Thank you for your understanding. Thank you for looking.
