Fixer beads are made in the Czech Republic. They are pressed glass dimensional tiles that have four holes. There are two configurations of Fixer beads, vertical drilled holes and horizontal drilled holes. Fixer beads are designed to fit around and hold Rivolis and Cabochons with a groove on the inside of each bead. They also work well in other beading/stringing designs adding structure to pendants, earrings, etc.
