Set of (6) Sterling Silver Japanese Boxed Champagne Bubble Poppers - These were made from 1925 until 1940 and they were made in Japan. Each piece contains a different figure on the top. The stems are made to look like bamboo. The sterling pieces extend out to make a Champagne bubble popper - they were made to make carbonated beverages less gaseous. The hand-made wood box is covered in a faux light grey leather and this box has the original brass hinges.
