KLASSÉ dressmaker pins are a longer straight pin for general sewing when you want more reach through layered seams and thicker areas. This pack includes 200 pins in 38 mm (1 1/2"), made from nickel plated tempered steel for a smooth glide and steady holding during cutting and stitching. Keep pins away from the needle path, remove before sewing over them, and store in the case to keep points protected.
