Mnemosyne N183A spiral bound note pads by Maruman feature a durable, black plastic front cover with rounded corners, a heavy paperboard back cover, and are bound with twin wire spiral binding. Mnemosyne note pads feel good in your hand, look good, and most importantly are wonderful to write on. The N183A Notebook measures 5 7/8 inches wide by 8 1/4 inches high and has 70 sheets of perforated, fountain pen friendly paper. The pages are blank, with a page title/number block at the top page on the front only. Paper is 80 GSM- lightweight, but heavy enough to take most fountain pen inks without bleed-through. The paper is properly sized for water-based fountain pen inks so that no feathering occurs. Each Mnemosyne pad has a yellow blotter page inside the front cover. The high quality paper works equally well with ballpens, roller ball pens, highlighters, markers, and pencils. Mnemosyne is the Greek goddess of memory and her namesake notebooks give you a place to put down all those task to be remembered today.
