11/0 seed beads. These vintage seed beads were made in Czechoslovakia. The sparkle of these seed beads is amazing! The color is so brilliant, and their transparency just further enhances the overall sparkle. These are a must have! There are 12 strands per hank. These seed beads are all temporarily strung in hanks for your seed beading and weaving convenience. Simply tip your needle through the string and take off what you need. This is one of the nice features of beads sold in hanks.
