Thanks to ChristopherJ for starting this poll! We've contacted the vendor on your behalf and they've made the Datamancer Typewriter Keycap Set available.
Please disregard the font suggestions i made. Thought you were looking for font suggestions for the keycaps like these keyboards. I did not realize you were referring to actual products until i clicked over to the discussion tab. Please remove or let me know how to (i don't see a way to remove)
