The 10 needles pack is for sewing machine. They can be attached to this handle but are too short and thin for manual sewing. I do not recommend to use it. The big needles are more or less ok, one of them is stainless, but the other two are carbon steel and look like starting to stain. Besides, the marks to attach to handle aren’t straight. Handle slot is not well made, just two bent and different size curs. I expected mor quality on workmanship. Shipping in 3 weeks
Thank you!!!
