NAO-ART Purchased by my mother in 2023, used a few times. Stored after being shampooed at home. It seems it cost about 160,000 yen. There is a product warranty in the 7th photo. The warranty period has expired. It's not jet black, but rather brown. It smells like shampoo. PRISILA 9,800 yen Unused. It's not jet black, I think it's dark brown.
