This is the $130 Adesso AKB-636UB Desktop Mechanical Typewriter Keyboard. It's got the look of an oldschool typewriter, but with all the marvels of modern technology like spill-proofing, n-key rollover and Kaihl Blue mechanical switches. Unfortunately they don't make a bronze version to match the rest of your steampunk desk. Me? I don't have a steampunk desk. I don't even have a desk at all. I'm writing this from a hospital bed. "Are you okay -- what happened?!" Somebody was selling an old hospital bed on Craigslist.
Keep going for a handful of closeups.
Thanks to AlexAnder, who apparently has a capital letter right in the middle of his name. How prestigious!
