This pencil sharpener-eraser is a great gadget.
It is useful to be able to sharpen a pencil and not to worry if a waste basket is nearby. I also like the fact that has the eraser attached.
Its circular design gives it a "Yin-yang" feeling of balance.
The orange wavy design on the plastic divider gives space for the thumb to be position in one side and the middle and/or forefinger on the other side to have a good grip of the gadget when erasing or sharpening.
I like the idea that in one side enables you to disappear what you want to vanish and on the other side enables you to create whatever you want to communicate visually.
