lol. I have a zelda-themed hard pouch for my 3ds, but it's a majora's mask n3ds xl. though, it's kinda confusing with my switch. I have two: one normal, hackable system and an animal crossing one. I got the animal crossing pouch, but I like the one I bought a while back that's zelda themed. it's much more spacious and it works with either system. it's just not the right game.
I only managed to get it, because a friend told me where to buy. I had to get the pouch separately at a different store. I'm hoping to get that 3d world system, but I might have to settle for scalping prices. on the bright side, the animal crossing switch has come down in price a lot, so you might look into that.
btw, I think that zelda carrying case (it's not a pouch) fits accessories and games too, but the animal crossing pouch is just for the system.
