Sorry this has taken so long. Had problems getting into VV for over a week.
Anyway, do they clink when you tap them with a tooth? Or other item? Lucite clunks, glass clinks.
And most definitely 80s.
Thank you. It clinks on my teeth and I do believe it is glass. The clinking is why I asked. Sort of found it odd to find glass like this from the 1980s. Thank you again. I took a break but also could not get into VV for a few days. I thought it was me.
