New secret pen:
Two pens are assembled, with one pen for writing and you can not see anything. The if you use the second one to paint on the marks you just made, the handwriting appears.
One end of the pen can be used to write, and the other end is a lamp. Using the pen to write, you can not see anything. But when you use the other end with the light to shine the handwriting, it will appear.
