Seconded. Duralex glasses come in many sizes, stack perfectly, break into pebbles and look fantastic. When I broke a Duralex glass in bed and was showered with pebbles instead of shards I switched to nothing but Duralex. We also now use their storage containers and mixing bowls.
I’m frequently able to find them at Goodwill stores, and Cost Plus carries them. Just look for the circle logo!
