Notebook-style blackboard with chalk, A4 size, made by Nihon Rikagaku

This is a notebook-style mini blackboard from Nihon Rikagaku, a long-established chalk manufacturer.
I think it would look stylish to use it for memos, or to write titles, schedules, menus, etc., and place it on a mini easel.
It's not an original item, but chalk is included.
It has been opened, but is unused.
