Brightly coloured wristbands are used essentially for two purposes identification and or security.
When your message is custom printed on a wristband it acts as a highly visible billboard enabling security to identify you from a distance as a patron of the event & you have a right to be there.
Wristbands should be highly visible & tyvek wristbands are designed to be non-stretch & non transferrable which helps to guarantee one person, one entry.
Rubber stamps can’t be seen from a distance and the imprint may be misused & transferred to other patrons.
Cable ties cannot be printed like a wristband & have a one way ratchet which can only be tightened.
If some patrons decide to prank their mates & pull on the cable ties, they can tighten to a painful degree & the event organiser may then be exposed to OH&S issues.
Printed wristbands are designed with the patron & security in mind, offering a cost effective & efficient means of supporting your security measures.
