The original ZZZip-Fly was released in December of 2003. Two years later, Dif-e-Yo released two special editions. Pictured here is the Collectors Series Zip-Fly. Like all ZZZip-Flys, this one weighs in at 58 grams without the rubber weight ring, and 66 grams with the ring, with KonKave Bearing and Difpad response. This one is also nickel plated.
Look carefully and you can see the text "Dif-e-Yo ZZZip-Fly #06" is engraved on the rims, as is the Dif-e-Yo logo on the center hub. This special edition was shipped with special stand and exotic wood, felt lined box.
