A project many months in the making, I’m excited to launch the MD Notebook B6 Slim Pen Addict Edition!

This B6 Slim notebook works as well on my desk as on the go, and the MD PAPER handles everything from fountain pen ink to pencils perfectly. Here are the full specs:

MD Notebook—made simply for writing. The MD Notebook is designed to let you experience the comfort of writing and the character of its materials as they are. MD PAPER is used not only for the pages, but also for the cover and endpapers. The cream paper is gentle on the eye and formulated to resist smearing and bleed-through while delivering an exceptional writing experience. Its unwrapped, unadorned construction is a defining feature. The notebook is bound with durable thread stitching, offering both flexibility and strength. It opens completely flat, ensuring a smooth, uninterrupted writing experience from the first page to the last.

The Pen Addict logo is boldly embossed with orange metallic foil. This edition contains the 5mm grid layout, inspired by traditional Japanese manuscript paper. Once filled, each notebook becomes a uniquely personal volume—place it on your shelf alongside your favorite books.

Optional covers can be purchased from MD PRODUCT USA Online Shop.
