Well, you don’t know until you know. Just realized this “pair” I’ve had for years is not identical.

One of these is 1/8” taller than the other and the shorter one has a wider base:

1-5/8” v. 1-7/8”. Appears the foot of the taller one has a more cupped base rather than the flatter shorter glass. My guess is it was a manufacturing issue and we just never noticed.

Please review all photos and feel free to make me an offer on this “special” pair. Thanks for your interest.
