I've forgotten where I bought this, but I think it was from Nishimatsuya. I was mainly using a different bath chair, so I haven't used this one much. The light green bath chair is also in good condition, but the shipping cost seems quite high, so I'm only selling the mat. If anyone wants just the mat, please let me know. I'll wait a few days and if no one wants it, I'll throw it away. There are no major stains, but please check the photos.
