Our Stickers and Magnets are made of high quality, long lasting vinyl. They are strong enough to last on a car or water bottle, and they have a UV protective coating that prevents fading from the sun. They range in size from 3x2 inches—4x2 inches. All stickers are now sent without wasteful packaging and they are labeled with our information. If you would like your stickers to include tabs for easy hanging, please let us know.
