This is hand-made vac-stack borosilicate tubing in COE 33, made with American color and German clear glass. It comes as a single tube about 12 inches long, with an outside diameter between roughly 15mm and 26mm depending on weight. The color is a spicy pepper tone lined inside clear glass, so the pattern sits under a smooth outer layer. It suits lampworkers and glassblowers who want consistent, ready-made color tubing instead of pulling their own vac stacks.
