Rob, yes Awagami make interesting papers, but none of their papers come close to the weight, translucence, and surface character of the Epson Japanese Kozo Paper Thin. There is no support sheet technology in Awagami's production, severely limiting the weight that can successfully be put through a water based ink jet device. You have to see Epson's Japanese Kozo Paper Thin against the thinnest Awagami Kozo and then you can make a comparison. :-)
This is also the first natural fibre inkjet paper in the world that you can fold and the image won't crack. Think Origami!
