Pez 'errors' come in many forms. Some are actual flaws or errors in the dispenser itself, or it can be an error in the packaging. Here are the 'errors' I have collected so far ..... the whole top row and the first 3 from the left on the second row are Pez packaged on the wrong card for that series. The next 5 are what we call "naughty Pez" - they are turned backwards in the packaging, or what you can say they are having a 'time-out'. Then I have a TMNT with his bandana off his head, a Hudson Cars with the car loose from the dispenser. The bottom row are: empty Christmas card, Blind Wonderwoman, TMNT with no bandana on him nor in the bag, and TMNT with his mouth sewn shut.
