A scary vision for a child (and parent!): a day on the beach and suddenly you can't find your parents anymore. It's not necessary to search for long anymore, due to these reusable id wristbands: plastic bracelets with a water resistant label on which you can write your child's name and your mobile phone number.
Indispensable for school trips, holidays, during day trips or anywhere children can run off at an unguarded moment.
Also grown-ups wear the wrist bands: for instance fanatic sports fans who go for long distance training trips alone or heart patients who write their medications on it.
Do you need any help or advice?
