These match the corresponding Clairefontaine writing paper. If that's something that matters to you, like it is for me, then these are a must! The one unique thing I love about these is that they come with self-adhesion to the flap. No more licking and getting paper cuts on your tongue! (not to mention more hygienic) I love how simple and understated all the Clairefontaine products are, very chic and modern.
