To the cardboard box? You might check your LGS, they'll probably have some, but if not Amazon sells them: 800 ct box
Although apparently they are technically 800 ct rather than the 1000 ct games stores claim they are. Oh well, close enough.
Care to show us the cardboard boxes you bought? Is it similar to these BCW Amazon boxes?
I organize as follows:
I used some off brand clear sleeves originally, and they stuck together like warm gum on a window. Upgraded to Eclipse sleeves, and it was night and day. I upgraded from there to Dragon Shields from there and I will never turn back. Durability is amazing (no dings, dents, tears), and the clear front looks like glass.
They're BCW Boxes. See : http://www.amazon.com/gp/product/B00E46J6PQ
