I found this tablet with 18 different kinds of paper in it, before each new section of the paper it describes the origin, where it made and more specific information about it. I do not recall where I got it but it was online, Goulet or Jet Pens maybe.
Its cover says
Premium Paper
Find Your Pen Friendly Paper
Fountain Pen Friendly
Collection
It was not inexpensive but its really cool to try all these.
Hard backing front and back
