They may have acrylic in the description but since they are also called "glasses" instead of something like "cups" , tumblers", or "drinkware", and with their being priced similarly to the rest of the actual glassware listed on the site, I feel they are deceptively marketed. They are plastic cups. I expected them to be glass and unfortunately missed the return window due to a death in the family. Customer service advised me to list them on Facebook Marketplace to get some of my money back. Didn't love that.
