3 different insulators.A toll with SDP's and bodasious amber swirling and a white potstone to boot! A few halved drips is all that's wrong with this guy. Next is a very great colored B in a yellow green olive. Dome chip on the back but just an awesome color! Third is a clean bright blue Star with a fingerprint type depression on the top of the dome. Only $35.00 for all 3 shipped in the USA.
