Since I also own a keyboard and mouse in bamboo, I could not help me to acquire this pretty little desk calculator made of bamboo also. The good thing about the calculator is that it does not need any batteries. It is operated solely by a solar cell. The keyboard is very easy to operate and the display is sufficiently large. It has the four basic arithmetic operations and a% key - should therefore be used only for simple arithmetic operations. All in all a stylish part that not everyone has. The workmanship is very good and the price is for what you get in order.
