These neon green paper wristbands accent any type of venue that boasts a black light area. Each box of 500 has a series of 5 digit numbers allowing you an accurate count of guests for every event. Simply remove the protective covering from the sticky section at the end and securely fasten around ones wrist. These quality wristbands will stay in place for the duration of the night (or day) and are not interchangeable should you worry about underage guests switching out their wristbands. Measuring 10 inches in length, they are adjustable to fit any size wrist.
