A4, this notebook first premium has it all: a blanket with a slightly rubberized coating which, when opened, reveals pages small eggshell color tiles, two bookmarks, one black and one white and one folding pocket to store business cards or other document, sealed by a rubber band, it also has a pen holder. What I particularly like are the 5 initials of the last page guaranteeing acid- and chlorine-free paper and association with responsible forest. All this pushed the price but not beyond reasonable.
