The English US characters are spread onto non-transparent - matte vinyl by typographical method. The characters/letters are printed underneath protective coat, on a high quality film. This method is used to prevent the ink from smearing or coming off as a keyboard is being use. Save money on buying a new English US keyboard. Instead, use these stickers as it is the easiest as well as the most inexpensive way to replace (or renew) the existing characters on your keyboard. The matte vinyl the stickers are made of - guarantees complete absence of glare under different angels of lighting. Thus, all characters are printed underneath the film ( also known as a reverse printing), which in turn, makes stickers even more durable. Each set of the English US stickers is compatible with different models of Notebook, Laptop or desktop keyboards. The keyboard stickers will not slip off, tear, nor fade away even after years of use. The stickers are self-adhesive, which allows them to be evenly applied onto a keyboard without damaging its keys. The adhesive coat will not ooze, harden or wear out with time. The stickers are intended to simplify your job, make communication even more satisfying as well as less time consuming while doing it on a computer.
