Reflective tape is made of waterproof PVC material with commercial grade adhesive. It can resist dirt, grease, grime, rain, and sun-fading and stick excellently even in the wet cold snowy weather. Warning arrow patterned is Yellow & Red or Yellow & Black , alternating. It works great for vehicles, trucks, boats, road marking, tractors, bicycles, motorcycles and mailboxes. It provides that extra visibility when needed on dark roads and catches the light from any angle.
