It’s not everyday we see a well designed “colorful” office supply but the World Time calculator by Jinvas executes it very well with its own unique design.

The World Time calculator is an ergonomically designed calculator from Korea that can also serve as, like the name suggests, a world clock and a calendar. Although a simple calculator feature would’ve been enough, it nevertheless incorporates its other features rather nicely with colorful design.
