Can't tell from the box.
I've still got my case from a decade plus ago, and...well, the back's different.
But then I realised that might be because my box is Australian, so the formatting on the black bottom half on my box could very well be different to the formatting on an American or European box.

True, yeah; the cartridge should have a serial code on the front (i.e. my Platinum cart - which I bought from a physical store - has NTR-CPUE-AUS), and, if it hasn't worn off over time, another code written in monospace black on the back (my cart has CPUEN1J11).I'd be wary, if you ask for pictures of the game and they specifically avoid showing you the cartridge...
I hope these are sealed copies otherwise the prices are outrageous

some of them seem so but not sure of all
Yeah and all of them are remade too hehe ....These are some insane prices, even by middle east standards.
Anyway boxes don't tell us much, though I have yet to see someone fire up the shiny colours printer (mind you 240USD, or that plus 4 or 5 others to bring it to a grand, would be about what it takes for me to pay attention there).
Pokemon. Red case so OK start. Image too grainy for me to make out the stamped numbers on the label. Can't see the PCB. Colours on the label look OK but again the image is not great, and for 130 USD you would get my best printer effort rather than print on a random label.
If there are fakes then they are some of the best I have ever seen.
It is however an awful lot of money for pokemon when flash carts exist.
Flash carts unfortunately cant connect to the ds games even everdrive gba x5
I don't know if pokepatch ever made it to cheat form but there were various GBA flash carts you could dupe DS flash carts into speaking to.
Even if not if you only want to transfer some over you can dump saves, use emulators and flash saves back.
