Made by Metro Industrial Co., Ltd. This is an MSU-501H kotatsu heater unit. Manufactured in 2022. Used for about two months during one season. I'm selling it because I bought a new one, so I'm offering it to someone who is looking for one. It works without any problems. Everything in the pictures is included. It's relatively clean because it was used for a short period of time, but Please understand that this is a used item and no returns or refunds will be accepted.
