Model Number: YH650 Color: White Included: 4 screws and 4 fasteners each Purchased through a construction company, so there is no brand name printed on it, but it is believed to be a product equivalent to TOTO. I am listing it because I am not using it at home. This is a set of 2, but if you would like to purchase a single item, I will sell it for 2000 yen each. Please consult the comment section.
