Most of the keys (well, certainly all the 1U keys) on the older Model M keyboards are 2-piece, with the text printed on a keycap that snaps onto a stem. Will that be the case with these keys, or are they all 1-piece keys? Or does it depend on which key set?

I ordered the F77 w/HHKB and split backspace layout, and additionally the front-printed function keys, and set #2 for the numpad. Which (if any) of these will be 2-piece?

I also ordered the following five 1U keys from https://www.modelfkeyboards.com/questions/question/are-there-any-photos-of-the-hhkb-layout/ and would like to know if those are 2 or 1-piece:
Backspace
Enter
