Tritan from Eastman 12 Piece Unbreakable Tumbler Set - Amber

They are right, very sturdy and attractive glasses. Very happy with them, not so much as a tiny crack so far. Great price as well!

Well, I bought these for a Christmas present for my 82 year old Mother. She loves iced tea and water. But the 20 oz. cups are huge! Way too big for her. : ( I returned them.

Even my husband loved these! This is my second set - tossing the crappy ones.

These were a gift--my mother loves them.
