This is a professional sewing machine from baby lock, known for their serger machines. I received it from someone, but I'm using a home sewing machine, so I haven't had much opportunity to use it. I would appreciate it if someone could make good use of it. It has been serviced and oiled by a sewing machine repair shop. It can sew thick materials, such as hemming jeans. For those who understand that it is used, thank you. Please consult with me about the price.
