I have been using this special high quality card stock ever since I lived in Japan. It is A4 size 160 gr weight. The quality of this paper is superb and provides great format for inkjet printers. Much better than the stuff you get at an Officemax or Staples and it is in
A4 size so you can print many of the excellent files for this size.

Note: You have to register as an individual before allowed to order, but that was easy and simple.
I just placed an order for 3 packs, so lets see how long it takes to get it ( I selected USPS ground shipment.
