Using these cartoon decals is a breeze. First, clean the surface where you want to apply the decal to ensure it's dry and free of dust. Then, carefully peel the decal from its backing and place it on the desired spot. Smooth out any air bubbles with a credit card or a similar flat object. As for care, avoid using abrasive cleaners on the decals. If they get dirty, you can gently wipe them with a soft, damp cloth. That's it! Enjoy your unique cartoon decals.
