The Midori Refill pack for the Brass Pencil contains three HB pencils and two erasers.
The refill is meant for the Brass Pencilholder, made of solid brass. It's composed of two parts. When “closed” the pencil mirrors a bullet casing and measures 98mm. When “opened” it measures 149mm, which fits like a glove. The eraser at the tip of the brass part can be replaced easily when finished.
