Berry Festive bead mix is primarily Czech and Asian beads, some machine cut for extra sparkle, some fire polish. There is a bit of designer plastic beads but I'd say 80% is glass. Beautiful, deep, rich colors ranging from jet ab to cranberry including many shades of purple in between. A very useful mix with lots of practical approx 4-8mm beads, along with some big chunky focal type beads as well. This mix will completely delight you! 4-5 ounce packages, we weigh generously. Get them while they last! When our mixes sell down, there is no more of that particular type.
