Blue and Yellow Border Bright Peel & Stick Year Stickers are made of waterproof vinyl. These signs are outlined by a border, making them really stand out on a windshield. Each 4-digit year sticker is slit on the back for easy application. Stickers are neatly shrink wrapped in packs of a dozen with a cardboard backer to prevent curling during storage. Each sticker measures 14"W x 5 ¼"H.
