Set of 8 CORDIAL glasses

Vintage? stemware. I know these are at least 20 years old. Set of 8 small wine / cordial / port / Nick and Nora style cocktail glasses. Perfect condition. No chips, cracks or water deposit staining. They make a beautiful ringing sound when flicked, so possibly crystal. These belonged to my great aunt, but I don’t know much about them. Approximate measurements 4.75” tall x 2.3” diameter at opening. About 2.5” at widest point. Just over 2” diameter base. Stem is approximately 2” tall. Soda can shown for scale. Will be safely packed for shipping. From a non-smoking, pet-friendly home.
