KAMsnaps&reg; 100 Transparent Clear KAM Snaps Size 20 (1/2 Inch) T5 Plastic Snaps Fastener No-Sew Button Punch Rivet Stud Popper 100 sets clear KAM snaps. Size 20 = 1/2" cap diameter. 1 set = 2 caps, 1 socket/female, 1 stud/male. Clear sockets have a wider mouth (where the stud snaps in) compared to colored sockets. As a result, clear sockets should not be combined with colored studs. If installing with a table-top press, socket and stud dies with the "extended lip" are required. If installing with KAM hand pliers tool, clear snaps require more pressure to secure compared to colored snaps. Snaps are commonly used on clothing, cloth baby diapers, bibs, towels, and other embroidery, craft, sewing and household projects.
