The Moleskine Medium Black Sketchbook is bound in cardboard, with a 'moleskine' cover having rounded corners and an elastic enclosure. The 88 top-quality acid-free pages are thread bound, and the notebook includes an expandable inner note holder made of cardboard and cloth. Each Moleskine journal has a ribbon placeholder and removable card with the history of Moleskines. Made using pigmented pulp, this rich sketch-grade paper stands up to eraser use and provides a great base for all dry media, such as Moleskine Drawing Pencils, pastels and charcoal, as well as Moleskine pens, fountain pens and markers.
