Shitajiki (下敷き, literally under-sheet) is a Japanese word for various types of materials placed under a sheet of paper for writing, either to prevent marking on the sheets below or to provide a better surface for writing. They are usually referred to as pencilboards in English.
Highly collectable in Japan. They can come in many designs but they mainly are in anime or manga.
Hard to obtain outside of Japan and some are rare in Japan. This was shipped directly from Japan to me in the UK.
