Classic prong-back magnetic snaps in 18 mm (3/4") provide a quick-close fastening for bags, accessories and heavier-weight garments. The silver finish blends with matching hardware and resists tarnish. Each snap installs with two prongs and a washer—mark the placement, cut tiny slits, insert the prongs and fold them flat to secure. Use for flap closures, pockets and organizers where a secure but convenient closure is needed. Pack includes 2 snaps.
