William Hanna and Joseph Barbera's Pens

Origin
These pens were used by the famous cartoon creating duo William Hanna and Joseph Barbera to make characters such as The Flintstones, The Jetsons, Yogi Bear, and much more. The two animators were known for taking various cost cutting/time saving measures in their animation. The most famous of these measures is the wraparound background in which the characters would pass by the same few frames of background art over and over again.

Effects
These two pens were granted the ability to warp space and trap a person in singular location where they will only be able to move within the same confined space. The pens work by holding them up to eye level where the pens can be perceived as a pair of walls. This not only sets up the space in which the trap person/s can move, but also makes the user able to shorten, lengthen, and even move the warped space Prolonged usage of these artifact will warp a person sense of reality and make them believe that the whole world is a work of fiction, a cartoon in most cases.
