GMK keycaps speaks for itself.
One thing I'm utterly disappointed having owned this being my 3rd set is the fact they would come with missing keycaps. After waiting for 3 weeks (almost 4), it was missing an 'ESC' key. Oh well.. guess this is how artisan keycaps are being used.
At first I was appalled at the thought of spending $100 on basic-looking keycaps, why spend that much on a color I could get from a different manufacturer? But after seeing these in person, they are simply amazing. The color is super deep, something that reminded me of the "blackest black" color that absorbs almost all light. The theory that GMK got their hands on such paint is beyond me, but it's probably the closest you'll get. The only complaint I have is the lack of basic 40s split space support, but at this pricetag it's something you'd expect for them to skimp on. Fortunately, there is a 40s kit for these, but you'll have to resort to the aftermarket to get your hands on them.
