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