Customizable calculators appeal to math whizzes and the number-challenged alike, but why would you want to give them a plain one when you can give them a translucent one instead? Our See Thru Solar Calculators use the same technology but add a dash of excitement.

These items are solar powered and therefore charged by a mighty amazing power source called the sun. They re ultra-slim, lightweight, and easy to read, making them ideal for any demographic from students to accountants. The large digital display should cut down on squinting, too.

We ve always thought that mathematics needed more color, and that s why we decided to offer these custom solar calculators.
