Each 3.76" by 6" sticker is die cut and printed on a CLEAR durable and weatherproof thick vinyl that protects the sticker from scratching, rain and sunlight. These stickers are also dishwasher safe so, slap them on anything from your favorite coffee mug to your trusty Rite In The Rain and be confident that your 9/11 Never Forget Clear Sticker will be there to stay.
