The Bloc Rhodia No.11 notepad is A7 in size (7.4cm x 10.5cm), and has 80 sheets of 7mm-ruled 80g/m2 white vellum paper that is made in France. The pages are bound by a single staple near the top edge in portrait orientation, and each page is finely perforated across the top about 1.35cm below the top edge of the paper for easy detachment. As with other Bloc Rhodia notepads, that means the available writing area is rather less than the nominal size of the notepad; in this case, approximately 13% of each page is lost to the binding above the perforations.
The paper is quite typical of this line of Rhodia products in terms of smoothness and whiteness, and generally speaking it is quite resistant to feathering, ghosting and bleed-through when used with fountain pen inks. I can see shading even when writing on it with very fine nibbed pens. There's a bit of 'woolly' outline when writing on it with Sailor kiwaguro pigment ink using a Stub nib, but the effect is quite inconsistent from one page to the next. (See images (2a) and (2b).) I attribute that to the obviously uneven application of coating to the paper, even on the recto side. Even though I didn't feel more feedback or friction resulting from that, at some random spots on the page the coating is so lacking and/or defective that half a word may cause terrible feathering and bleed-through see images (3a) and (3b) even though the other half of the word doesn't.
On the verso side the inconsistency in the coating is more evident; using the same pen and ink on the same spot, to write exactly the same thing with the same handwriting technique, on consecutive pages can give noticeably different line widths and/or levels of ink spread and feathering. (Compare images (4a) and (4b); (5a) and (5b); and (6a) and (6b).)
On where the coating is not defective, ink can take relatively long to dry. The marks seen in image (7a) are not the results of bleed-through from the writing on the verso side of sheet #3, but just smearing from touching the verso side of sheet #2.
Frankly, this isn't a product I can find any reason to recommend, even though I'm usually a Rhodia fan. It's expensive, the size is impractical unless you have a really small pocket that can nevertheless handle a 1cm-thick notepad, the unavailability of 13% of the already small paper surface for writing is annoying, and the paper quality is poor on account of the inconsistent coating, not that I expect anyone to put such a notepad to use with calligraphic or artistic endeavours.
