These 2 inch- Anger and Caffeine stickers have been through very rigorous and (somewhat) scientific "Hydroflask testing" to ensure their durability and give you and your new stickers the best possible chance for a long and happy future together. At 2 inches, these are the tiniest Anger and Caffeine stickers we offer, and are a great size for helmets, cell phones, or water bottles that have a small empty space that is begging to be filled with something awesome.
