I have lots in my inventory but it not to the point where I can't do trades mainly because I don't really have multiples of the same item

i keep my copies on my mule, i have to have at least 2 ove every item though i try not to have more than 4 of any except events and commoms of different colors

I have multiple of the same common just for the different color options

Even if you did it for the sole sake of finding the limit, I think it loos like a pretty neat collage! ^_^
