This is the SAWAWA Microfine Bubble Shower Adapter from Ernest Co., Ltd. I had to store it because it wouldn't fit properly after I replaced the showerhead at home. The retail price was 9,980 yen. There are no noticeable damages. For those who are looking for one. Ernest is a company from Tsubame-Sanjo, Niigata, known as a major production area for metal products such as cutlery and cooking utensils.
