Since people are asking me to post some of my keycaps,
here is how my Leopold FC500R Red Switch look like:
With 2 sets of PBTs white and black inserted partly each set,
and some red blank ABS R4 Roll key.
and this is the Red Blank Keycaps for R4 rolls.
4 different color spacebar,
The white one is PBT, But cannot be use on Leopold zzzz
The Black Blank keycaps, which can fit into Leopold perfectly.
and these are 2 sets of PBT,
one white with laser print,
another one is black with purple paint.
which is what is left of those that I plugged into the Leopold for the moment.
and last but not least, my HHKB Pro 2,
with the gray modifier and orange Realforce key set.
