kplminThis holds a lot. I keep all of my clairfontaine stationary, G Lalo, a bunch of cards, in it, along with 2 packages of A5 Tomoe River paper. Plus I can stick at least 4 Visconti 6pck pen cases in it. You could carry 1 1/2" thick of file folders (legal sized). It's very versatile and I love mine!
