This is Hanaduri’s notebook Edge Blue Gugim Folio Insert A5 Plain. Can be used alone or as an insert for any A5 size notebook.
This notebook is made of Hanji, the traditional Korean paper made from the inner bark of Broussonetia papyrifera known colloquially as paper mulberry, a tree native to Korea known as dak. This material is strong but soft to the touch with the natural texture of the fibres. In addition, Hanji is a durable and versatile material, while retaining its lightness and beauty.
