Pair of PEZ Whistles with crystal heads, one crystal green head on 4.9 US Patent Made in Hungry neon orange stem, one red crystal head on 5.9 US Patent Made in Hungry neon yellow stem. There were only 150 each of these even made. They are super hard to find for sale, now is your chance to own them both. Both PEZ are in mint condition. I have other PEZ listings with other Whistle PEZ and some other really nice vintage PEZ. All of the PEZ I am currently selling is from my personal PEZ collection.
