You'll need to under lite this light blue B 145 for the best results of bringing the fizzy swirls to life. I've used the sun as my bright light source in the pic. A bright light box would be ideal. The fizzy pretty much surrounds the entire threads and then seperates and devides below both on the inner skirt and outer and looks much more intense in person. This insulator is in mint condition. There is excess glass sticking above the surface from tools used for moving the insulator while the glass was still cooling. Asking $35 shipped anywhere in the lower 48 US States. Will assist shipping to other countries.

I accept Pay Pal in a non fee mode, person checks and money orders as forms of payment.
