Prism Pack Rainbow Makers - 10 Pack
Just add sunlight! Place prismatic vinyl decal on window to bring rainbows into your home, office or car.
Includes 10 prismatic vinyl decals ranging from 3-5". Decals are reposition-able and remove from glass without residue.
I recommend that you place the decal inside the window rather than outside in the elements. It works either way, but will probably have a longer life on the inside.
