|Clairefontaine Linicolor spiral notebooks.|
They're very cool. They come in various sizes but this is the one I like. It's 6 3/4 inches by 8 5/8 inches -- just the right size for tossing into a bag or briefcase. And of course the notebooks contain excellent, thick, smooth Clairefontaine paper that is more than suitable for fountain pens -- it's heaven. Best of all, the plastic covers are slightly semi-transparent, so you can see your handwriting on the top page. And wait till you feel the cover! It's got a ribbed design that you cannot stop touching. It's literally fun to drag your finger across the plastic.
Truly, these are the notebooks they use in heaven. They seem to be permanently on sale at writersbloc for $6 instead of the stated $10 price. Six bucks is totally worth it. You must buy one right this second! Here's the link. They come in five bright colors but you can't specify which one you want. It's a grab-bag thing. However, if you buy five, they give you a pack containing one of each color.
Hurry, go buy some!
