Fabulous Lauscha Stringers in 2 to 4 mm. The factory has not made this in years and if they did the price of materials today would be a lot higher. Clear stringers are the best way to encase a bead. Soft clear melts easily on a hot head torch or a small torch. Lauscha factory charges more for thinner rods due to extra labor involved in handpulled rods. Minimum half lb.
