I got the Webnotebook at the Chicago Pen Show and I really like it. I gave up Moleskines a while back because I couldn't find the right ink to use in my fountain pen that didn't feather and bleed through.
The webnotebook has a sweet black cover on it which feels sort of like it is padded and feels great in the hand. The paper is NOT typical Rhodia paper. It is an off white/cream color in the style of the Moleskine. On the lower right corner of the right hand page is a very small Rhodia logo that is mostly unobtrusive while still leaving enough space for a page number if one is in a habit of numbering their pages (as I am). I will be numbering this book in the upper outer corners.
So far I have written with two inks in the book and find feathering to be nearly unnoticeable. Bleed through has only occurred with a very saturated ink in a very wet nibbed pen. Aside from the fact that I was using grid paper in my Moleskines the lined pages in the Webnotebook is the ONLY drawback I see with this product. I can foresee the Webnotebook to take over my daily use pocket notebook activities.
I also picked up a couple of ePURE notebooks. I got two large size and 1 small size. I have been writing in the large ePURE and find the paper to be very much like the Rhodia we have come to love. Large size is 5 3/4 X 8 1/4 inches; the small is 4 1/4 X 5 1/2 inches. One of the most saturated inks I own is the new Noodler's Nikita and it is currently in a rather larger italic nibbed Parker "51". It lays down a very wet near triple bold line and it is the one ink that has completely bleed through. But in my experience bold wet lines on all Rhodia papers have a tendency to bleed through, so nothing new about that.
With any luck at all we will see these on the American market sooner than later. We just have to keep our fingers crossed. In the mean time those of you who just can't wait for the US import, the book is available in Canada and via a couple of British web sites I know of.
