I believe this is a rare item, but I have absolutely no idea what it was used for – a mysterious Teflon presser foot. There are no manufacturer markings or model numbers, and I couldn't find anything using Google Lens. However, I'm listing it in case someone out there is thinking, "This is exactly what I've been looking for!" If anyone knows what this is, please let me know in the comments. ☆ I polish each presser foot before listing it, but please understand that these are used items and may have scratches or cloudiness on the metal surface. ☆ I have other presser feet for sale as well. I welcome combined purchases and will discount each additional item by 100 yen if they can be shipped together. #IndustrialSewingMachine #PresserFoot #StitchGuide #SewingMachineAttachment #JUKI #brother #Janome #ZipperFoot #SUISEI #Suisei #SmoothPresserFoot #TeflonPresserFoot
