Awesome Numbers

Add your initials, a serial number, or other identifying text to your projects with these heavy-duty steel stamps. Hit them with a hammer to leave an impression in wood, leather, or soft metal. Each 36-piece set includes letters from A to Z, numbers 0 to 8 (9 is 6 upside-down), and an ampersand. Choose from 1/4″ or 5/16″ sizes.

Millions, billions, trillions, quadrillions, septillions… these kind of large numbers are really hard to wrap your mind around. The guys at Riddle attempt to put some of these numbers in perspective using real world examples of things that occur in such quantities.
