This isn't just a calculator. It's a legendary piece of minimal design created by Dietrich Lubs and Dieter Rams, two titans of their industry. Their far-reaching influence has been a huge inspiration point for an incalculable (pun intended) number of designs for furniture, tech, and personal goods, including that iPhone in your pocket. And real-deal examples of Rams' and Lubs' design work are hard to come by, which makes this beauty all the more special.

If you crunch numbers often, ditch whatever dime store design you've been using and add one of these to your desk for a clean, beautiful, and iconic infusion of style.
