These glass telephone pole line insulators make a beautiful paraffin oil lamp. A hole is drilled in the top and a glass "stopper" with a long lasting fiberglass wick is inserted. The bottom is sealed with clear epoxy and will not leak. Insulator style is CD 155 in clear. Other colors blue and aqua available on first come basis. I can also make your insulator into a lamp, custom pricing. They make an excellent Christmas gift! $14.95 plus buyer pays $4.95 in priority shipping and handling for US destinations. Check, money order accepted. Oil not included. Peace.
