Rare Piece to acquire for your German collection. This is called a German Corkscrew due to it's semi corking nature between the transparent aqua blue glass and the milky white semi opaque glass. The original rod was made from half aqua and half white then Twisted into a partial Corkscrew when it was made off the cane. This particular one measures in at .57" and is very clean. Only a micro pin tic seen under loupe and a small tool touch A exquisite rarity you might never get your hands on again! I was lucky enough to acquire a rare board set of these a few years back. Only a few remain and this one was one from my personal keepers. See last couple pics for some group shots of the lot
