Stringers are threads of glass pulled from remelted Bullseye COE 90 tested compatible sheet glass. They are often used as decorative elements on fused glass pieces, or for delicate detail in flameworking projects. Because of their thin width, stringers can be bent using the heat of a candle. Each stringer is approximately 17.75" long. A tube of 0.5mm stringers contains approximately 350 stringers, a tube of 1mm stringers contains approximately 123 pieces, and a tube of 2mm stringers contains approximately 50 pieces. Tubes are packaged by volume.
