I found this notepad in my favorite stationery store in Montreal, Nota Bene. It's called Exacompta Bloc Faf. The bottom is a piece of metal with rubber backing (so it won't skid) and it holds the pad of paper by two screws. Very simple design with a utilitarian, industrial look. It holds 200 pages and you can choose between graph paper and solid white.
I bought these notebooks earlier this year in Paris. I can't remember the name of the store, but it was on Rue Pont Louis-Philippe. Probably the best street to go to if you're looking for fantastic stationery. The man who works there (maybe owns it?) was sitting at his desk quietly doing calligraphy on some wedding envelopes. His work was absolutely beautiful.
I especially love the notebook pictured at the bottom which illustrates proper and improper greetings, the close-up picture shows the funniest one "excessive reverence".
