Nitori Insulated Kotatsu Futon

I am selling this item because I ordered the wrong size.
It is an unused item, only checked for size.

Please refer to the table in the second image for compatible kotatsu tabletop sizes. This item is listed as Large Rectangular.
I am also selling a compatible kotatsu, so please take a look if you are interested.
