The Wooden Cube digital alarm clock displays the time in red LED. A simple and stylish design in the shape of a wooden walnut cube, it also shows the current temperature, which, like time, flies. It has 3 levels brightness, and gentle LED lights will display in the smooth wood surface, even at night you can clearly see the time. You can choose AAA batteries or USB cable as a power source. I recommend USB cable because batteries will be drained pretty fast. Wooden Cube clock looks amazing in your bedroom or on office shelf.
