Impossible Pen by TENYO | Close-up | SEO MAGIC

(Effect)
A pen is placed on top of a closed pen case, and surrounded by a frame and cover.
After appearing to "cut" through the pen case, a knife is used to push the pen downwards.

Oddly, a clicking noise is heard. When the cover is removed, the pen is found to have vanished.
When the cover of the pen case is removed, it is seen that the pen has appeared inside the case!!
