Core Sample 950 mL Steel Bottle

Beautiful bottle and very durable

I have two Cognitive Surplus bottles now, I love the cool sciencey designs and you can just tell these things are made to last a lifetime. Absolutely gorgeous products

Lovely product

Good quality and perfect print for my paleo nerdom

Cool look, poor function

Very nice aesthetics. However, differently from other thermo bottles the cap is fully metallic (and hence looses constantly heat) and it cannot be used as a glass (so one has to bring an additional glass/cup for hot beverages). A pity, because the design with the geological periods is really cool.
