This is an awesome Macbook decal of the Seattle Skyline for all Macbook sizes 11"/13"/15"/17". All of our Macbook Decals are made of vinyl rated for 4 to 6 years of outdoor use. All decals are 100% waterproof, and can last a very long time depending on use and wear of the decal. For greater adhesion choose a glossy finish. Each decal is easily removed without residue (which makes changing them on a regular basis easy and fun). Please be aware that these decals are not reusable and cannot be repositioned once applied. This decal was designed specially for mac computers, but can be applied to PC's and most flat to semi-flat surfaces. If you are ordering for a PC please specify the dimensions of your PC in the "note to seller" at the time of checkout.
