Braille stickers are a very economical option for creating a bilingual Braille keyboard. | The stickers use an easy peel-and-stick method to install. | The Braille stickers are printed on clear Lexan so the original key legend shows through; this allows you to add Braille stickers to your existing keyboard so that it becomes a bilingual keyboard (Braille) and the original language of your keyboard. | They will not ooze adhesive, dry out, or damage the original keyboard key. | (Windows PC)
