OMG, I love these glasses So much I just ordered another set of four!! They look and feel just like crystal clear glass, but they are lightweight, unbreakable and exceptional plastic!!! They wash so easily, stack well and don't make a lot of clinking sounds!! They are beautiful, well made and the plastic is thin like glass and sleek like glass feeling!!! There are some things that just taste better in a Glass made of glass rather than plastic, like a cold glass of Milk!!! But these glasses are perfect for my glass of milk!!! I really just love them, I plan on replacing all the 'glass' products in my cabinet with lightweight unbreakable beautiful products like this Tossware Reserve!! Thank you!!!
