Approx. size 9/10cm UVDTF prints can be used on various substrates, some are - Glass, metal, wood, paper and ceramics. I recommend hand washing drink ware for long lasting decals. Care instructions - Let the decal cure for approx 48hrs before use and hand wash for long lasting colour and decal. How to apply: - Wipe your item down with isopropyl alcohol to clean any greasy marks off. - Use a squeegee or scraper to press over the decal firmly front and back to make sure it will stick to the film. - Make sure you trim down any excess film to make sure that it wraps around your tumbler/item nicely. Peel the film - Position the wrap on the item, do this with care as once it adheres it cannot be moved. I recommend a cup cradle for easy application, - Use a squeegee to push out any air bubbles - Peel the backing off slowly at a diagonal angle, ensuring that no print pulls up or rips. - Once it is on, firmly press over with squeegee to make sure that it doesn't have any bubbles.
