Using these Celtic Border Decals is super easy. First, clean the surface where you want to apply the decal to make sure it's dry and free of dust. Then, carefully peel the decal from its backing paper and stick it onto the surface. Smooth out any air bubbles with a credit card or a similar flat object. When it comes to care, avoid using abrasive cleaners on the decal. A soft, damp cloth is enough to keep it clean. In cold weather, be gentle when handling the decal as it can become a bit brittle. If you need to remove the decal, slowly peel it off at an angle to avoid damaging the surface underneath.
