It’s Sedimentary…

Love this glass! The white shows up great when filled, and makes drinking iced coffee fun and educational!

Hard to pack in field; otherwise outstanding!

Beer. The holy sacrament of geologists.

Great glasses!

Ordered these for my son, who happens to be a geologist. They are very nice glasses.

Super high quality. North American made. Most novelty items like this are hastily constructed and printed onto poor quality glass. These glasses are impeccable and are worth the money.

Good design

I like the design and it does a good job of holding liquid. I wish they made this in a one pint beer glass style.

Great find

I love the detail, the science here! Looks best with a dark beverage in it.

Cool Glasses but NOT Pints

I expected them to be pint glasses. Turns out they are highball so I was a bit disappointed. The idea was great and humans as a mass extinction is a great (and subtle) surprise.

Hi David, I'm happy that you liked the design; thank you for the compliment! I'm sorry for any confusion. They are highball/drinking glasses and the listing only features pictures of that style glass. If you'd like to make an exchange or return please send us an email ( My apologies for any inconvenience. All the best, Cognitive Surplus
