Rose and there was me thinking it was men that measured wrong
But Margi, do you know why women are such bad judges of distances (size)? :24:

touche Carolyn..... that my excuse !

At 2" I think you were right on with the shot glass idea. I've got some tucked away somewhere that are kinda similar and don't know what they are. Don't think mine glow though. Have to dig them out sometime. I agree with Lustrousstone on likely origins.
Would like to see your glasses, and maybe they glow also........I can lend you a purple ruler. :spls2:
I am not finding anything -- Wonder IF these glasses *could have been* part of a beveled decanter set ?? I dunno know......
