3mm Three-Fold Hemming Foot I believe this is a genuine manufacturer's product, but the details are unknown. Used item. For industrial sewing machines and professional sewing machines. I have many of these, so I will only list the part numbers and information written on them, omitting the specific uses. Occasionally, they may have been shaved or modified. I will note this if I notice it, but there is a possibility I may miss something, so please check the images carefully before purchasing. If you purchase multiple items together, you will receive a discount of 200 yen per additional item. This applies only if you purchase through the system's "bulk purchase" option beforehand. If you purchase multiple items separately, each will incur shipping costs, so discounts are not available. Please be aware of this. #IndustrialSewingMachine #ProfessionalSewingMachine #Attachment #ThreeFoldHem
