1 Crystal Chick in Egg 2005 PEZ Convention PEZ Dispenser. These dispensers were given out in the registration packets for the St. Louis PEZ Convention aka Annual National PEZ Convention. These have never been used. The Crystal Chick in Egg PEZ dispenser comes loose and ready to display. They are in mint condition. If you don't know crystal just means clear plastic. They will look good in your PEZ collection. I sell a lot of PEZ, check out my other eBay listings!
