Using these alien robot 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. Align it to the desired spot and slowly press it down, starting from one end and smoothing out any air bubbles as you go. When it comes to placement, you can put them on cars, trucks, boats, or even on walls. Just be careful not to apply them on surfaces that are easily scratched or damaged. For maintenance, you can gently clean the decals with a soft cloth and mild soap. Avoid using abrasive cleaners as they might damage the decal. And if you ever want to remove the decal, slowly peel it off at an angle. It should come off cleanly without leaving much residue. Have fun decorating with your new alien robot decals!
