It is actually quite solid, heavy glass. The cup looks a lot better as well as here in the pictures in real even. In the dark there is light breaks in it, and he sparkles really nice. Unfortunately, I was the cup so enticed to drink whiskey, that I for the first time in my life wg. Had to throw up alcohol. Sorry, but is so. Since then, I look the cup with a sense mishmash of "wow, looks great and yeah, our first encounter has given me decent vomiting and abstinence of about 2 weeks." (Now it's back :-)
Conclusion: This cup is his money something of value. Looks Classy and high quality and it is also.
