This is an extra-large skull-shaped beer mug that I obtained about 30 years ago. I believe it was a souvenir from a casino in Las Vegas. It's heavy because it's made of thick glass and is large. The design is of a pirate, although it may be difficult to see in the photos. Size: Height: Approximately 16cm Rim width: Approximately 11cm Width: Approximately 12cm Depth: Approximately 16cm I am an amateur and do not have any specialized knowledge. I cannot accept returns. Please understand that this is a long-term storage item from a private individual before purchasing.
