Yeah, they do that. U get a gba box with only a cart inside, usually theres a carboard thing to hold the cart etc

but also like games that don't exist. Pokemon black chaos, and 653-in-1 carts etc. Fake games made by editing the rom replacing some texs and sprites with new ones

i got a nice 'armani' wallet for 8 eur and i could get a pretty cool (VERY bright) green laser pen for 7, but it was flimsy and i was out of cash. It burned when i shined it on my hand and u could see it a reaally long distance
