Czech glass beads are some of the finest in the world with fire polished rounds, rondelles and a huge variety of sizes of shapes. These are very popular popular beads because of their unusual finishes and blends of colored glass. They are hand made by the people of Czechia in Europe and it is not uncommon for every bead to be slightly different in color. Their sizing and hole sizes are uniform. While fire polished beads are normally called "rounds", they are just very slightly oval. Your purchase of these beads also helps the Beads For Good charity supported by my supplier to help children in Mexico and other parts of the world. More beads are being added regularly to this collection, so check back frequently!
