Review: Solid - Good quality glass have had for a few years now.
Review: My favorite flask! - I LOVE this flask, it’s so versatile I use it for everything! It’s thick, it seals tight and despite how much I’ve abused it, it doesn’t have a chip on it! It even survived being used for boiling a solution and then dunked into liquid nitrogen without a cool down period.
