But, I was really talking about "cable sleeves", which could be a DIY project, using whatever you might find.
I'm kind of a "go naked" laptop user, so a little bit of goo is just part of the game, I think. And, I also tend to put away original cables, if possible, as I usually prefer other lengths (maybe shorter, maybe longer, depends on my use) where Apple's cables may not necessarily be the best choice. And some are black. Got a neon pink braided cable that I just like. (bought two so if one fails (or won't come clean), I got that spare.
