Edited 08/23/21: I've had this for almost exactly two months now and the letters have faded. Black is NOT dirt. This is wear and tear I've even tried to remove with nail polish remover. Can order replacement. You can simply order a new keyboard. Rice. 1. Wear and tear of the original keyboard. Rice. 2. Keyboard skin straight out of the box. he's just over a year old before my letters started to fade. My first attempt was to pull them back with a white pencil. Don't try to pull back the letters no matter how artistic you are. An oil-based marker will fade in about a week. I read in reviews that the "glued" letters slid across the keys, detached from the keyboard, and stank. So I didn't want to go that route. Then I found the K350 skin. Whatoooooo?!?! For the price I couldn't go wrong. I received it in mint color. You just slide it over your keyboard and it snaps into place by itself. It also reduces the "clicking" noise of the keys (sorry for my jargon) and if it ever gets dirty you can become a deli counter for those of us who casually eat breakfast, lunch and dinner on our keyboards for washing lose weight. So if the letters got erased from your keyboard, this is the solution for you! I am very satisfied with this product. Until Logitech finds a way to stop the letters from disappearing, this is the best you can do! Arrived within 24 hours of purchase.
