WTB : Black 24mm buttons

Sanwa or Seimitsu. Doesn’t matter. Need 4 of them. Lizard Lick takes a month.

Sanwa does not make OBSF-24-K or OBSN-24-K.
Sanwa does not even make OBSN-30-K.
Only available is OBSF-30-K from them.

Just Seimitsu for now makes 24mm Buttons in Black.
In both PS-14-D and PS-14-DN.

Ok then, I guess these can only be Seimitsu buttons then. Anyone got?
