If you can factory reseal them, then they have no excuse not to refund you.

Resealing the iPhone seems pretty hard after looking at an unboxing.

The newer models yes, they are designed to break as soon as start tearing one open.
Airpods gen2, older iphones are resealable with some shrink wrap

Edit:
Actually, you CAN re-seal the new apple watch 6 - 100% I am holding one now and it is possible.
Carefully remove the "pull" label thing off the packaging without damaging it.
Reseat the watch box with shrink film.
Slice the 6 lines/ wholes at the top and re-glue the "pull" label thing.

Not easy, but it CAN be done 100%

You will need pof shrink film, a heat gun, and an impulse heat sealer. Probably 50 to purchase the lot, but then you can hit up multiple stores for the iWatch
