It's a cylindrical slide rule that is compact enough to fit in your pocket. I can't even think of anything better than that.

3 versions included: one with inset text, one with raised text, and a plain version with no text. Personally I like the one with raised numbers for the way it looks, prints, and its functionality.

Fun for parties or meetings of model railroading clubs. Impress your friends. Win new friends. Stun your enemies with your mathematical wizardry. Get a promotion at work. Find a mate and get married and have kids. Become the president, prime minister or divine leader of whatever country where you live.

The possibilities are quite endless. Print one now. You will thank me.
