These wristbands are 10" long and 3/4" wide and each box contains 100 wristbands. Wristbands are tough, waterproof, non tear and non stretch. Bands contain a very strong adhesive and have tamperproof slits making them impossible to remove in one piece for another person. Security wristbands are perfect for admission to concerts, sporting events, VIP parties, festivals, carnivals, arcades, trade shows, seminars, nightclubs and many other events where crowd management is required.
