It is true, that this is not fountain pen friendly, however if you are a pencil
aficionado, this is the "holy grail". I have this small notebook paired with a
Pentel Sharp Kerry mechanical pencil. It really is an amazing combination. I use
it for a visual journal and while mechanical pencils are my primary tool for
this notebook, I often use Prismacolor Verithin colored pencils, Palomino
Blackwing, Blackwing 602's and Blackwing Pearls, and various high end drawing
pencils in 4B and 6B for writing and illustration in this notebook. The pages
erase well with high quality plastic and kneaded erasers as long as care is
taken. I also regularly use paper stumps for blending. Generally speaking, most
high quality pencils will work perfectly on this paper, provided the leads are
not too hard. As a rule of thumb, HB or softer (2B and HB work extremely well).
This is a great pencil notebook and I highly recommend it.
