The Habanas are great little notebooks with a sturdy yet flexible cover, elastic closure, and back pocket (which I think could be eliminated - I never use these pockets). The paper is a pleasing off-white tone, a welcome change from the bright white of many other notebooks. In the lined version, the lines are about 6mm apart (just right) and are a pale grey colour that makes them very unobtrusive. The lines do not run to the very edge of the page.
The paper is smooth and thin. All of my pens write very well on the paper, although, due to the thinness, there is some showthrough with all my pens. The only ones in the writing sample that bled through were the Pilot V5 Hi-Tecpoint (the worst offender), the Pentel EnerGel (very slight), and the Sharpie Pen (very slight). No feathering at all - all the lines were crisp and the colours bright.
I love my Habanas, and I was very sad to see that my university bookstore no longer seems to sell them. Luckily, I know of one stationery store in my area that still does. I do, though, have a question: are the Habanas sold in Canada different from those sold in the United States? I know that the packaging is different. This has always confused me, so if some kind person could enlighten me on this I would be very thankful.
Overall, the Quo Vadis Habana is an excellent notebook that remains one of my favourites.
