You know we can't be like everybody else. These are not the same stickers as you find at the bike shows. They are Reflective. That's right. During the day they look the same as everybody elses but when light hits them at night your message will be clear! This sticker / graphic is available in 2 sizes. Helmet size which measures approximately 1.25" X 3.5" and bumper sticker size that measures approximately 3.75" x 10.5". Reflective graphics produced with a high-performance retro-reflective vinyl with engineer grade quality that meets the ASTM 4956-99 specifications. Not only will your message be seen at night it also adds a little safety as well.
