One-hand calculator

What is the sound of one hand calculating?

I can't tell you but it looks very elegant.

From the website:

Famed robot designer Tatsuya Matsui created this slim calculator released by stationary maker Kokuyo.

Not only sleek and cutting edge, but also very comfortable to use with just one hand.

Although the possibilities are endless for a one-handed calculator, it is especially good for business people on the go, leaving your other hand to take notes, and convenient for taking shop inventory or orders.

Features:

• 10-digit display

• Display shows date and time

• Intuitive arc-shaped key design

• Slim design: 32 × 162 × 12mm

• History of previous calculations appear at bottom
