Retain heat long. Surprisingly sturdy as well. I dropped one from a foot height on a stone countertop and it survived. Impressive. Look great too. Transparent glass helps - easy to stop my manual espresso machine at the right time not to over extract the shot.

It was a mistake I bought. Very small just wasted my money

I bought them for my husband who enjoy to drink espresso in the morning. He really liked them because it is light, transparency and even cute with the zwilling mark.
