Octagon-shaped Octo-Tags from ACCUFORM SIGNS are attention-getting for ‘STOP'. The large headers reinforce that caution must be taken, and checklist and information (previously filled out) to be reviewed before entering the area. ACCUFORM SIGNS thin and flexible 10-mil, pulp-free PF-Cardstock tags are more durable than traditional cardstock, and will not crack, distort, or shrink. The matte surface is scuff-resistant and easy to write on with pen or marker. Top has 3/8" plain hole with stronger pull resistance than patch-reinforced traditional cardstock tags.
