Static Cling signs and decals are great when you want to be able to easily remove the decal. Great on glass, mirrors or monitors. Static clings are printed in full-color with or without a white background on an 8 mil vinyl. Specify when ordering if you will be using them on the inside or outside of the glass. Printed for use on inside of window unless otherwise specified on order. Need your cling to stick to another type of surface? Try our Re-stick-its!
