Question: are these glass or plastic?
Document: This is one of the greatest bargains you'll find in a set of margarita glasses. If you want real glass instead of plastic at a bargain price, this is the set to buy.
For barely more than the price of throw-away plastic glasses, this is a nice medium-sized glass that will be much more durable. The storage box that they come in will keep them safe, and give you convenient storage of the glasses.
I bought these for a work party as they weren't that much more than plastic ones and the reviews on the plastic ones seemed like a lot of work (gluing the steams to the glass etc). These were a hit, although I hated cleaning them afterwards!
i received these glasses yesterday and i immediately called a friend for an impromptu margarita night. the glasses were just the right size and weight. They are sturdy without feeling heavy to hold. There's nothing fancy about them, but i like to use glass over plastic when i entertain small groups. the price is right so i won't freak out if something happens to them. I am looking forward to taking them out for weekend get-togethers.my favorite thing about this set is the storage box.
Great glasses at a great price -- really made my margarita party feel much classier than using plastic cups, for barely more than the cost of plastic cups. Highly recommended!
Caught in a rush for a surprise birthday party that serving plastic cups would have been ridiculed, I got what I paid for. Certainly will never grace Martha Stewart or Neil Berkus' table(s), but, it prevents itself from a complete tacky affair. I was already chastised by my &#34;living far beyond my means&#34; friend, MCW........so hopefully, if you decide to purchase these, you are of sound mind and body.
Beautiful set and well priced as compared to glass sets found in other stores. Well packaged and I loved the storage box that it is mailed in.
These are quite sturdy and good quality - when I was expecting thinner glass for the price. Comes in a nice storage box with dividers to keept the glassware safe. Would make a nice gift, but I kept mine for my home!
Great for having guests. Persnally i like a bigger glass when drinking with one or two others but this is perfect for partys. I have the margaritaville mixer and one batch fills about 6 glasses. Ive hade them for 6 months with weekly use and not one has broken yet!
I was unsure about the size of these glasses, so I measured them with water as soon as I got them. I poured 8 oz (1 cup) of water into the glass and it filled up right to the rim. I think a 6 oz serving would fit perfectly! These glasses are well made and don't feel fragile in your hands.
Answer: Glass. They are super nice. I love them
