as suspected

very good news for sure

it appears to be from first kr molds ... pin peg high in the ring grooves
great price means they can be changed more frequently if worried about longevity
HELLO .... even a choice of tolerance/cylinder clearance

I see that PJME call the skirt coating "teflon". As far as I know (despite its self-lubricating properties), real Teflon repels oil.
I have had many piston skirts coated with Molybdenum Disulphide and this coating attracts oil. However, I've also been told that some piston makers/suppliers describe their coating as "teflon" even though it may not be.

I believe there are other piston skirt coatings available which also attract oil. If anyone buys a set of these pistons, could you please put some oil on the skirt coating and see whether it appears to be attracted or repelled...and let us know?

Thanks & regards,
James
