All of our stickers are printed and cut in-house and by hand. Each sticker is printed on high-quality vinyl sticker paper using only the best inks. The stickers are then laminated and kiss-cut. Stickers measure 2.5" on the longest side! Our stickers are durable and waterproof and work just as well being placed outdoors as in. They make great additions to water bottles, laptops, or just about anything else with a clean flat surface to stick to.
