Some amazon returns require an explanation while others dont. My guess, they took the default or went through the drop down to one that didnt require any actual reasoning.

It is for this reason I have stopped buying some things like Hard Drives (almost always get sold as new but are refurbs or used), or computers. Even when labeled as used amazon allows certain things, like glittery dbrand skins to still quality as “pristine”. Also there is a new thing where they will come wiped, but had been registered in Azure/Intune/Apple MDM and thus will still be locked or reporting in.
