Besides the fact that drawing with a 3-D pen is a great way to promote creativity and playfulness, a 3-D pen is also good for motor skills. It leads to better handwriting, a more precise control of their limbs and a firmer hand. After all, a pen remains a pen.
Children (and adults) can think of the best things. Do you need more conviction? The 3-D pen can even be used to make working objects. There is already a working plane made with a 3-D pen. If they can, you and your children can do it too! So be creative, and create some great things together. Your imagination is waiting for you.
