Our Bottle Stoppers are made from the finest and most beautiful woods we use. They are: Tiger Maple, Cherry, Walnut, and Maple Burl. Our mechanisms use solid stainless steel with rubber gaskets to seal the bottle. Our stopper mechanisms won't discolor, flake, chip or rust like most others do because ours are made from surgical stainless steel! More pictures of individual stoppers coming soon! Call us for our current selection.
