1to3 shop has only sent me genuine bands. I have bought 25 bands from him and every single one has been sealed and genuine.
@Pitch is also correct. Every knockoff leather loop I have ever seen does not have the size markings and/or the “natural leather” text with the icon. They also do not come in Apple retail boxes. The band fakers are exceedingly lazy and do not bother to make convincing fake boxes.
Edit: I just realized you meant the flash loop. It hasn’t been delivered yet. I will get it Monday.
@Pitch is still correct as I’ve only seen one possible fake sport loop with size markings. I shall let you all know when I receive flash and will post pics.
Edit 2: Oh boy, this guy that sold me the flash loop does have an obviously fake black silicone case listed. I will need to look very closely at this flash loop when it arrives to authenticate it, particularly with that fake electric pink with size markings earlier this week. The fake case:
