Update February 5, 2018: I have been using stickers for almost two months - 4 pieces in total - and the S and D stickers are already peeling off in the corners. I'm using Modge Podge hoping to extend the life of the stickers until I find a better solution for my keyboard. It only took me 4 stickers to replace the worn out ASDW keys on my backlit gaming keyboard. It fits a little less than the key, which isn't a problem. My only concern is that the corners of the stickers will curl up after so much contact that they will eventually rub off. The white ones on the stickers are NOT transparent. I have a backlit keyboard. The light is barely visible through the sticker. This is a trifle compared to not seeing the erased keys on the keyboard at all - just a ball of light. However, it's nice to have full keyboard keys again. I'm very glad they finally fixed those eyesore of the keys.
