I’m a big fan of unbreakable glassware made of Tritan plastic and we have several pieces of stemware made from Tritan. I have intentionally dropped them just to demonstrate how tough the material actually is. I especially like that the plastic is BPA-free and doesn’t form fine cracks ( “crazing” ) like acrylic does when its put into the dishwasher. These 10 oz Rocks glasses are nicely made and nest together well to save space in the cabinet. Although they are clear, they do have a faint bluish cast to them which I think makes it a little more obvious that they are made from plastic and not glass. I tried to capture this coloration in the included photo – Tritan on the left side and an piece of glass barware on the right side - however, its difficult to capture the subtle color in this image. The other thing you can see in the comparison photos is the generally thinner wall of the product vs the barware. Overall, I’m pleased with the set and I’m not too concerned about someone realizing they are made of plastic and not glass.

It's plastic—but it's also a solid plastic (Tritan), that feels sturdy and will last a while. Overall, these are well made cups with a beautiful art deco design and amber color that makes drinks a little more fun. Appreciate that this comes with 4 pieces in this set rather than just 2 pieces like a lot of other sets.Not sure what old plastic cups were made of in restaurants that seemed to last for years—probably something horribly toxic—but these hopefully will last at least half as long. Other Tritan plastic cups have gotten "foggy" over time through the dishwasher. I assume these will be the same, but time will tell and I'll be back with an update if/when that does happen. Another concern is that the inside has a lip, so that will just be a little more difficult to clean/keep clean.

These are perfect for use on your patio, pool area or elsewhere where there is concern of potential glass breakage. These 4 tall plastic glasses are not only unbreakable, they look nice and not cheap in appearance. A feature is that when they are stacked, they are easily separated and do not stick together as other plastic glasses do. There is a ridge where the line is visible toward the lower half. The stacked glass sets on that ridge (of the lower glass) so they can easily be pulled out from one another without it being a challenge! Dishwasher and microwave safe, sturdy, nicely designed, and high quality. You will likely use them as your everyday drinking glasses inside -- and outside, too!

I got these primarily because I like the 1970's esque style. I was also interested in buying something made of Tritan plastic which is a new plastic developed to replace polycarbonate because of concerns about bisphenol A.So that already checks 2 boxes for me. While these are smaller glasses than one might think, I often use 8 or 10 oz glasses for drinking water around the house or orange juice so these will work perfectly for me.They are made in the USA, which is a plus in these times.They really don't look like plastic at a glance which makes them even more attractive. They are pleasant to drink from, the ridges are noticeable but not distracting.They do have an inner shelf inside which is for stacking so they don't go too far inside one another. This is helpful as you can save precious space on the shelf and not have to pull them apart later.They are maybe a little smaller than you might be thinking at 12 oz as you might remember the similar style glasses used at restaurants in the past at 20 oz but this is more of a single serving cup.

TL;DR Buy them, well worth the Price. They will last for years to come and you will be happy with them.This is an Excellent set of Tumblers and is exactly as the Product Page described. They are made of High Quality Tough Tritan Plastic and have been working great for me. The Tritan Material will last a very long time and will not ever absorb any flavors from what you put into them. They also do NOT off gas or come with any odor whatsoever. These are the same quality Tritan Plastic that my OEM Vitamix Pitchers use. They are tough and ZERO flavor transfer.This Tumbler measures 3.5 inches across the Top opening and 3.0 inches on the bottom creating a 0.5 inch taper. The glass itself is 3.5 inches tall. The line you see in the pictures is a perfect 4.0 ounce pour with 6.0 ounces above it if filled to the Rim. Also that line you see is where these glasses are thicker on the inside which allows you to stack these glasses without them getting wedged too tightly together or suction created which makes it a struggle to get them apart. When these are stacked you can take the top one off with one hand, no need to hold the glass below it to get them apart. These definitely look like Glass and the mouth feel is very close to glass also.I know how good Tritan Plastic is, but I really wasn't expecting these glasses to be so nice. The ONLY thing I've found on these is on the bottom outside of the glass, some of them, had a slight point from mfg process. It did not interfere with the glass sitting flat at all, but I took a spoon and rubbed the point down to smooth. Also, these glasses have a very nice rollback counter top back-splash curve all around the bottom on the inside. It's not a steep angle like some glasses have on the inside. This makes cleaning them much easier.I'm extremely happy with these and highly recommend them.

I love how these glasses look. They're the perfect meal-size glass. I like how smooth the plastic is, and how well-finished it is - not rough at all. I like how the ribs look on the side of the glasses. I like the color a lot - it's a classic, somewhat retro brown color, which I think is cool. There aren't any strange manufacturing artifacts on these at all. I'm very pleased with them. Recommended.
