This simple ruler is made of solid brass. A ruler is a simple tool that requires the delicate skills of a made-in-Japan craftsman. To make it easy to pick up and draw lines with an ink pen, one side is slightly raised.
Brass ruler that goes well with the Midori Notebooks and Midori Brass Pencil Case
This product is well made, sturdy, and flat. It's useful as a bookmark in a Midori notebook, and of course as a straight edge. It appears that the numbers and inch divisions are etched (engraved), so there should be no rubbing off of those marks and information. Great product overall.
