Gakken vintage Amechan Rhythm rare plastic pencil writing board.

Unused but plastic is open at the top so writing board is quite dirty/marked up from age.

Pencil/writing board is perfect for putting underneath your paper on your writing surface for smooth writing.

In Japan they are called "shitajiki" which is a pencil board that is placed under a sheet of paper for writing to provide a better surface for writing.

Approximately 9.9" x 7" big. Just about B5 size.
