You have to measure the distance between to two pole pieces that go under the high and low E strings.
50mm-standard spaces
53mm-F spaced
If the stickers say “SH-2/4”, no they’re not. If the stickers said “TB-2/4” then they would be.
It’s referring to the spacing of the pole pieces. F=Fender spaced, which is slightly wider. TB= Trembucker, which is Duncan’s name for F spacing.
You can tell the potential buyer that it’s purely aesthetic, which is true, but they likely won’t believe you.
I no longer have the box's for them but the stickers on the underside of pups themselves say this: 121DY SH-2N Neck and 121DY SH-4. It might help if he told me what guitar it's going in.... I can find out
They are standard spaced

Not purely for the looks only. Was a hair band guy running Super Strats and a Floyd back in the day so know why this was done in the first place. If you were running a Super Strat with a high gain amp doing a lot of bends and using the trem aggressively you lost some signal with your E strings at times because they were off the poll pieces. I was running a couple Carvins back in teh day with thier M22 SD mine didn't have the issue others running conventioanl pickups dis so Duncan and Dimarzio gave us the wider F and trembucker poll spacings ( at least those 2 were the first I saw who did) as a solution.
