Crystal Clear Ruler 15cm


This crystal clear ruler from Lion, a major stationery manufacturer in Japan, has become one of our most useful items. You can use it to tear paper, as a book mark, to draw straight lines, and yes, even to measure things.

We tried other rulers, but due to its totally transparent plastic, none of been as practical as this Lion RA-5. Other painted or solid rulers cover up the contents of the page, which is kind of annoying when you're trying to drawn in context of the rest of the page.

Another thing we like about it is the precision beveled edge, which we use upside-down to prevent smearing with felt-tip and fountain pens.

155mm long, 30mm wide, 2mm thick. Made in Japan.

  1. Love this ruler 5 Star Review

    In my review of the eraser shield, I mention it lives in a pocket in my planner. The ruler is the shield's BFF and lives in the same pocket. Measuring tool or straight edge or just for fun, another useful tool.
