Anyone who works a lot on the sewing machine also needs a lot of thread. Large spools of thread are often conical in shape so that the thread unwinds neatly even when sewing quickly and provides the roll with a stable hold. The Prym cone and bobbin holder consists of a cast iron base with a steel fixing rod for screwing in and a boom to guide the yarn. This means that you don't have to keep threading new thread into the machine for more complex sewing work. The cone and bobbin holder from Prym ensures sufficient supplies and always maintains the optimum tension on the thread.
