This is a special cover that gently wraps your MD Notebook. The transparent cover protects the notebook from dirt without ruining its appearance. It subtly protects your notebook from water and dirt without interfering with its characteristics. If you put the cover on with the glassine paper still wrapped around it, the inorganic feel of the vinyl will be softened. Because it is transparent, you can enjoy the cover design, illustrations, and writing as they are. MD Notebook B6 Slim size Cover With pen holder PVC (Clear) Size (Open): H181 x W228mm Pen holder: Inner diameter 10mm Made in Japan
