Here's an insulator I think every collection should have, therefore take this one if you don't already have one. Only damage is a minor shallow flake off the ridge of the hole where the wire ties to. Kind of hard to explain, but the damage isn't distracting at all. Marked PYREX on the Front, along with Made in USA, and PAT. 1,700,066 on the reverse side. Take it for only $11.00 plus shipping.
