From the CzechMates two hole bead system, these Czech pressed glass cabochon beads have a uniform round shape with flat backs. Their large hole size to bead size ratio makes them ideal for consistent bead weaving texture and multiple passes of fine beading thread, such as Fireline, Power Pro, KO Thread and Nymo.
