It's subjective, but "great form, terrible CMF" is how I characterized Azio's line of chunky, deconstructed Izo keyboards.

Their Retro Mechanical Keyboard line, however, is a bit more subdued. For the most part they stick to basic tones and a simple design language:

The version below is not actual copper, of course. The company says the keyboard frames are made of aluminum; they don't specify what the keys are made of, which make me suspect they're plastic colored to look like metal, but that's just an assumption.

Other materials used, according to the company, are wood and Napa leather. They even offer leather-wrapped mice.

Surprisingly, the palm rest that matches this Maple version of the keyboard is an actual block of Maple, and not the veneer that I assume the keyboards are made with; which explains the $60 asking price for the palm rest.

As for the keyboards, they run $199 to $299 depending on colorway. The leather-wrapped mice are $105.
