Einstein hollow face illusion paperweight is created by using the optical illusion. When you give a Einstein monocular look, you will see a lifelike Einstein appearing in front of you. Whether you see it by left or right, Einstein will turn in the same direction. Other than being a paperweight, the thick crystal acrylic is a beautiful piece of artwork that adds the flavor on your desk. Ease your mind and bring the relaxation temporarily when you are busy at work or study.
