compressed cork stopper
close
image This is a stopper produced by crushing natural cork into small fragments to make its performance even and compacting these with polymer. Although such stoppers have often come to be seen with imported wine, in Uchiyama's compressed cork stoppers cork is more densified and polymer used is a safe one. Therefore these have a performance of not collapsing for long. And they are stoppers cleared perfectly of the substance causing cork odor, unparalleled in the world.
