These custom neon billboard sunglasses will make for a bold and memorable handout for summertime promotions! These stylish shades utilize proprietary high-speed technology to print a full-color logo on specialized vinyl material, which features mini vision holes so you can see clearly through the lenses. The proper logo makes for an awesome presentation! For best results, the logo should be as large as possible since small copy may not be legible. Due to the nature of the holes in the vinyl, no two sets of lenses are exactly alike, assuring your brand a unique giveaway!
