Our stickers are printed on 4mm vinyl. We only use professional grade material. Our vinyl is UV and moisture protected for 2-3 years continual outdoor exposure.

Humper bumper is an offshoot of our parent company 'Sign Central.' We have been in the business of vehicle graphics for many years. We know our materials.
