Far-infrared heat therapy device Himawari Kazoku

This is a heat therapy device that a family member purchased about 3 years ago. It gradually warms up and feels pleasant, but I'm selling it because I can't seem to use it effectively due to my sleeping position.

It has been used only a few times and I believe it is in good condition. It has been tested and is in working order. Please refer to the 4th image showing the lamp lit up.

For details about the device, please search for terms like Himawari Kazoku or Botanic Laboratory.

I have disposed of the box and warranty, so it will be shipped wrapped in bubble wrap.
