This is a part for connecting the Pigeon Shuppot nose mucus catcher and the hose of the Merci Pot. I've modified it for my own use, but the hose size was different, making it easy to detach and inconvenient, so I bought parts and made my own. I'm offering the extra parts, so I hope those with similar problems can use them!
