Reflective stickers to improve night vision. Fluorescent stickers also improve visibility during the day. Made of prismatic polymer reflective film or from retro-reflective polymer film with glass beads with one side coated with acrylic adhesive and a protective paper pad. The package contains 4 pieces 1,3×21cm. Apply to a smooth, clean, dry surface, free of grease – we recommend using isopropyl alcohol. Apply to easily visible places. Before applying, adjust the size as needed. Do not touch the sticky part so as not to degrade the adhesive properties! The adhesive property of the stickers is reduced on matte surfaces! Do not apply to the braking surface of wheel rims! If necessary, clean the dirty stickers with a damp cloth. Store the package in a clean, dry place at room temperature, away from direct sunlight. This product is not a toy.
