I purchased this new online for about 2,300 yen and used it, but it didn't fit my shower head, so I gave up. I'm selling it because I bought a different product. The angle and direction can be freely adjusted, and I think it's an excellent item. I threw away the packaging, so please check the usage and size from the internet before considering it. The photos show everything. From the manufacturer's website: Make your shower more comfortable.
