So I sorted through the SP multisized bag and found a good deal of 2X and 4X multi-switch keycaps. These are designed for use on programmable POS keyboards and keypads, where they can be mounted on two or more adjacent switches and one switch can be disabled through programming. Except for maybe one or two keycaps, almost all of them are doubleshot. Fit and finish seem to be particularly good (for SP caps anyways), with sprue marks on the back (top?) side of the caps.
What's available for sale is pictured below, PM me with what you want.
Shipping will be around $5 to start in the US via Priority Mail. Prices for the keycaps are TBD, make an offer or wait for me to determine them. Please note that people have already PM'd me with requests, so they will have first dibs on certain keys. Keys will be marked unavailable as they are purchased.
THESE ARE NOT GOING TO FIT 3 STEM STABILIZED SWITCHES!!!
