KLASSÉ curved safety pins are designed for quilting, sewing, and craft projects where multiple fabric layers need a reliable temporary hold. This pack includes 60 pins in 38 mm (1 1/2") Size 2, giving extra length for thicker quilt sandwiches, batting, or bulky seams during prep. Work the clasp gently and keep pins closed when stored so they stay easy to handle and ready for repeat use in busy sewing rooms.
