Super nice Tillotson threadless. This is about as close to mint as you can find in a threadless insulator. There is just some light roughness and a few micro flecks on the base edge mold line (probably there from the day it was made). Nice clean, crisp glass in a very nice blue aqua color. Also a little milky olive junk in the glass. Just don't come much better. This one has been in my collection for a long time. I'm going to list a few really nice pieces for sale today. All these are from my collection and I don't want to sell them, but some unexpected expenses have come up so I need to get a little cash together. Please take into account that shipping costs are included in all of my prices. $450.00 for this one!
