Our stickers are designed with attention to detail and made from quality exterior grade vinyl that lasts years. Intended for use on clean, smooth, and non-porous surfaces, stickers are made from computer cut vinyl with transfer tape applied and ready to install. Once applied, the sticker has no background. Whatever surface you apply it on will act as the background. If applying stickers on a window, lighter colors (such as white) usually work best. If you have any questions, please contact us. We are happy to work with you to create a custom size or order and please check out our ebay store for more stickers and signs!
