This is a net to catch hair that goes over the drain strainer in the bathtub. I'm selling it because I no longer use it. There are 25 sheets in a bag, and there are 4 bags, so there are 100 sheets in total. They were stored for a long time on a shelf under the sink. There is dirt and foreign matter mixed in. (Photos 10, 11, 12) Some parts are discolored. (Photos 13, 14) I will ship via Yu-Packet Post Mini from Yu-Yu Mercari.
