If it can be said that a ruler is clever, we think this one qualifies. French visual artist Elsa Werth’s intervention on this engraved metal ruler is simple but transformative, like all the best solutions. She placed a mathematical operator in between each number and the product of this sequence—once added, subtracted, multiplied and divided—is equal to the actual length of the ruler: 30 cm on one side, 12 inches on the other.

We are delighted to be the exclusive U.S. stockist of this item.

Harper E. ★★★★★

The engraved equation on this metal ruler makes me smile every time I reach for it. It's sturdy enough to actually use for straight lines, not just a novelty, and the math joke lands perfectly with my coworkers.

Jacob ★★★★★

I keep this on my desk and it's become a quiet conversation starter — people always pick it up to work out the little math puzzle. The metal feels solid and the engraving is crisp, not printed on. Three weeks in, still my favorite thing I've bought for my desk.

Richard A. ★★★★★

The engraved equation running along the edge is a nice touch — it makes me smile every time I reach for it. Metal feels solid in the hand, not flimsy like the plastic ones I've gone through. It's just a ruler, but it's a genuinely fun one to keep on the desk.
