Can't Find Typewriter MX Compatible Keycaps

[Learis]

I got a cherry set recently, and liked how since they were so short it made typing easier. But then I saw pictures of typewriter mx compatible keycaps and was shocked at how short they were. But they're proving extremely difficult to find. Does anyone know of a place to get this profile of keycap?

This is the thread where I learned about this:
https://www.reddit.com/r/MechanicalKeyboards/comments/8mtvwi/need_lowprofile_keycap_set/

And here are two pictures, showing the height difference. In the thread it said that a vintage cherry keycap was shown for comparison sake.
