Using our checkmark decals is super easy. First, clean the surface where you want to apply the decal. Make sure it's dry and free of dust. Then, carefully peel the decal from the backing paper and place it on the surface. Smooth it out with a soft cloth to get rid of any air bubbles. When it comes to maintenance, just use a mild soap and water to clean the decal. Avoid using abrasive cleaners as they might damage the decal. Also, don't try to remove the decal forcefully as it could leave residue on the surface. If you need to take it off, use a heat gun on a low setting to loosen the adhesive gently.
