Keep Calm And Herp On. You are purchasing 1 sticker that can go on your vehicle, enclosure, tank, or anything that you would like to put it on. These decals are fun to add to anything. Decal size is in the picture. This decal comes in white. When you are ready to apply your new decal make sure where you are putting it is clean from all dust and dirt. A damp cloth with a little soap is usually all that is needed. Make sure all soap residue is wiped clean and dry. Peel off the backing, rub your decal in place and SLOWLY remove the top layer. If your decal starts to come up with the top mask layer put it back down and rub harder and try again.
