We have many unbreakable Tritan-plastic products which we use on the patio by the pool. While these Martini glasses from Bravario share that same durability, their true claim to fame is their Amazing appearance. The smooth curves and hourglass shape of the stem on these Bravario glasses make them look like real stemware made from glass. I would say that the shape is a blend of a coupe glass and a martini glass, with more of a curve to the bowl and a very thin rim that you do not typically see in plastic barware. The plastic is also clearer, with the molding lines being nearly invisible and an almost blue appearance that does a great job of looking like true crystal. These glasses are 8 oz in size, while many others are 10 oz; from a presentation standpoint, I prefer serving cocktails in a slightly smaller glass that appears close-to-full and that is easier to do with an 8 oz glass vs. a 10 oz glass. Overall, these Bravario martini glasses are nicely designed and well-manufactured.
