These 4mm opal fire-polished beads from the Czech Republic are fashioned from milky glass, creating a semi-translucent look usable in a variety of designs. These faceted glass beads are still made in small quantities by hand and are re-fired once produced to give them a sparkling touch. Due to the way they are made, there may be slight color variation from one batch to the next. Their 4mm size is ideal to use in any type of design.
