CGNENT stickers are made of high quality vinyl and are waterproof. They are great for laptops, cars, notebooks, skateboards, hard drives and anything else you can think of! Our stickers use a special adhesive that is removable without leaving any residue behind. This means you can move them over and over again without damaging your surface. You can also clean the surface with soap and water after removing the sticker to remove any residue left behind from the old adhesive.
