NOTE: Most Stickers come in several sizes, measured in inches. The measurement is taken on the longest or widest part of the sticker. For example, if you order a sticker that is 3 inches, it could be 3 inches long and 1/2 inch wide. Make your size selection from the dropdown menu, if the item has more than one variation, it will have a dropdown menu for you to choose also. These stickers are printed on waterproof glossy vinyl with another transparent vinyl laminate for extra protection. They are also coated with UV spray to help protect from the rays of the sun. They are glossy, waterproof & strong vinyl. They will adhere to most surfaces, mostly used in car windows. Smaller sized stickers are used in water bottles, cell phone cases, notebooks, laptops, binders, refrigerator doors, etc., almost anywhere. We make the stickers as they are ordered, that's the reason that we need at least 3 days before shipping. We print, dry for 24 hours, we treat for UV rays, dry again, we then laminate and then cut the stickers. All our stickers include tracking information. There is a barcode above your name and address and every time the Postal Service scans it in a different location, you the buyer will receive an email. Once it reaches you, it will say Delivered.
