The stickers were easy to stick on the keys. I cleaned each key with a small amount of cleaner applied to a cloth to ensure a clean and dry surface. In the photo there is only the "P" button that I put a sticker on and the rest are other stickers that I had and didn't need to be replaced. One reviewer reported that they looked bad, were of poor quality, and started moving after two weeks. I'll see how they work, but for now they're pretty transparent and their quality is good.
