Since 1932, the year BOJ patented this double-lever corkscrew, millions and millions of units have been sold worldwide. This corkscrew made in Éibar, Guipúzcoa owes its great fame to its durability, efficiency and its curious design, reminiscent of an owl. It is present in art museums as an icon of popular culture.

After years of research and development, the BOJ team has managed to manufacture a worm that is capable of extracting natural and synthetic corks more easily.
