They are supposeably only for sellers to give to their customers in case of breakages. Not supposed to be for sale of any kind.
I got a set coming as a prezzie from my mate who received a few sets, plus i think i may be lucky to get a Revyplier!
but i'm not sure yet, i'll show pics once the package arrives.
The cool thing i'm thinking of is using the Revy joints and using it on PVC figures that aren't poseable/articulated, and turning
them into figures! Imagine the possibilities.
