Review on Enhance Visibility and Safety with 42Pcs Reflective Stickers - Perfect for Helmets, Bicycles, Motorbikes, and More! by David Blackstock

DO NOT BUY! I used them for our bike helmets. Some of the smaller decals worked well and are still attached (who knows how long) but the larger ones detached from the helmet within minutes. When I tried to remove them it left a sticky, gooey mess! I used rubbing alcohol to remove it, which seemed to work but made the glue even tackier. I then tried nail polish remover which worked in the end but also removed the trim from my bike helmet. Terrible thing!
