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. Several strands are available and may vary slightly in size or color from the one pictured. Each bead measures approximately 4 x 8-9mm, with strands measuring approximately 29-33" long. This would make a beautiful addition to any beader's collection. Get them before they are gone!
