Thermochromic Rub & Reveal Film becomes translucent when the coating reaches 28C/82.4F or 31C/87.8F. To activate, simply touch with warm hands or rub with a finger or thumb. Great for masking secret images, colours or text!
These vinyl sheets can be applied to most smooth flat substrates - no hassle required!
Just remember to apply the sheet with care, ensuring each edge lines up with the surface you're covering to avoid air pockets from forming. Peel the backing away from the film a small amount at a time. Apply the film to the surface to be covered. Finally, press down with a smooth flat object like a plastic ruler or credit card towards the edge to remove any air bubbles.
