### ⭐⭐⭐⭐⭐ Great quality flask for many purposes
*by T***E on 8 October 2020*

We bought this for a custom wedding gift to a couple of scientists. It survived a plane flight, laser engraving, being filled with weird stuff and other types of abuse, so it definitely is strong as hell! You could also make funky cocktail glasses from these, or, you know, use them for science, haha.
