This is a Showa Nishikawa MuAtsu folding MuAtsu cushion, one black cushion. It is new and unopened. This is a non-sale item, a gift received when purchasing a MuAtsu mattress. Size is 35 x 35 x 3.5 cm, and it can be folded in the middle. It will be sent via Yu-Yu Mercari delivery. In my opinion, I use a commercially available MuAtsu cushion, but this is the perfect size for a small person. It's very lightweight, so it might be good for carrying around. It will be simply packaged with bubble wrap. #ShowaNishikawa #MuAtsu #MuAtsu #Cushion #Wheelchair
