The hair bows are made of grosgrain ribbon and tied in a tuxedo shape approx 4 cm in diameter. Bows are attached to our 30 mm stainless steel ribbon wrapped snap clip. Snap clips slide in and "snap" shut like a barrette style. Do not use in damp hair. This bow looks best on little girls 3 months to 36 months. You must have hair for this clip to work. Fine hair will work.
