I'm looking for one of these types of stylish MacBook keyboard skins:
But I don't want any of the keys marked. I just want blank keys, without letters/symbols.
Do any such products exist? I can't find any by looking myself.
Yes, There is one such unlabeled keyboard available that I have found: the Das Keyboard 4 Ultimate. It is an external keyboard and not a cover, but I think it's what you're looking for.
