Sliced Prosser Beads, otherwise known as button beads, get their name from their unique shape. These beads originated in the former Czechoslovakia and were made by pressing molten glass. They have been traded in Africa since the late 1800's early 1900's. We haven't had green prosser beads like these for some time. Several strands are available and may vary slightly in size or color from the one pictured. Some strands may have 10-20 beads that are not green. This would make a beautiful addition to any beader's collection. Get them before they are gone!
