Used. I am selling this as part of a family office clean-out. Apparently, it was previously used at an educational institution, and there are traces of sticker removal, imprints of the facility name, the educational institution's name, and markings indicating it was removed from the inventory. The inside is incredibly clean, as if no one has read it. Please be aware that there are imprints of the facility name, removal markings, and sticker removal marks. Maruzen
