I found this while organizing the storehouse at my parents' house. It's not from my era, so I'm guessing it's from around 1945 (Showa 20) or later? I may never encounter items from the same era again. Details are unknown. It's also unclear whether the pencils themselves were sharpened and stored, or if the manufacturer originally sharpened them to be ready for immediate use (I don't know about that time). One pencil seems to have a printing error or is mixed in out of formation. In any case, they are all in a state of readiness for battle (please judge from the images). It seems I won't be able to use them, so I will pass them on to someone. For shipping, they will be returned to their case, carefully prepared with packing materials, and dispatched. Thank you for your consideration.
