Perfect for cappuccinos
My husband and I both love these. We love how they are lightweight and how we can touch or hold them on the outside without burning our hands, and how they keep our espressos hot! We have used them daily for a year and have had no issues. We're careful with washing them, and have not shattered one yet.

Light Weight Is Both a Plus and a Minus
These very lightweight cups, made of some peculiar type of glass, has become one of my favorites for morning coffee because of my arthritic hands. However, my husband doesn’t like them because they are too light weight for him—he prefers the heft of traditional glass. However, as I learned recently, they ARE NOT SHATTERPROOF.

Love these mugs
The mugs arrived well packaged and I'm very glad I bought them. They are deceptively lightweight and hold just the right amount of hot tea. They keep the tea hot for quite a while. Much better than the heavy, larger glass mugs I was using.

Shatter easily.
This cups shatter easily. They are way too small. Thought they would be bigger.
