Nice size to start with learning how to use decals. I like this best on furniture but you can use this size on anything from scrap booking albums,blackboard, dry erase board, plaque, craft projects, car window, mailbox, and many more items. Add to painted canvas and make your own art. Can be removed, not saved. Rated for 5 years outdoors by manufacturer. Buy more than one and only pay shipping on first,each additional can be different colors convo us with your choice of color. The instructions on how to mount will be included or many people show how on Utube. Material needed will be a teflon squeegee bought for use on wallpaper however you can use anything to rub on, even your hand, smooth side of credit card, or a spoon but best results is with a teflon squeegee to get out all the bubbles. The larger size to size decals will need help to be hung unless you have done decal wall hangings a lot.
