Decals are pre-cut vinyl words or images meant to be applied directly to an object as they are, for example on a wall, mirror, door, or whatever else you might like. There are multiple color options available, they are removable and will not leave a residue behind. A stencil is a vinyl cut out that can be applied, painted over and then the vinyl removed, such as for making signs. Each type comes with a clear tranfer tape to help you position it just right as well as instructions. Not all options are available for all designs as tiny fonts and skinny lines do not hold up as well as decals.
