Review on 🚴 AGPTEK 3 Pack Reflective Stickers for Helmet Bicycle - 38 Pcs Reflective Tape for Motorcycle, Helmets, Bicycles, Strollers, Wheelchairs - Ideal for Hard Surfaces - 6.5 x 4.13 Inches by Tim Jenkins

Generally good reflectivity. Even on slightly curved surfaces (MTB front wheel forks and smaller seat and chain stays), the edges no longer stick to these areas after a short time. Even if you clean the intended surface thoroughly with a degreaser or alcohol, or try to bend it with some heat to improve adhesion, the edges will not stick to the underlying surfaces. If you wipe the surface with alcohol to clean it, or if you apply it to the surface and then try to peel it off to adjust its position, the clear outer layer (which holds the reflective material) will separate from the thicker white one layer . from underneath. They can be applied effectively to a well prepared PLANE surface on the FIRST try! I have not tested their ability to remain tacky to surfaces after exposure to water (e.g. rain, hand washing or pressure washing).
