These are sewing machine parts that I found while organizing my home. There are three presser feet, one of which has a roller. I believe they are for a home sewing machine, but I'm not certain. The photos contain all the information available. Also, I don't have the environment to test their functionality, so please understand that these are sold as-is. *I may change the shipping method from Rakuraku Mercari Bin to Yu-Yu Mercari Bin. If you have any issues with this, please contact me in advance. *I am an amateur regarding this product, so I cannot answer specialized questions. Dressmaking, handicrafts, sewing tools, handmade
