Lab-Quality
Used these for an experiment. They held up to high heat for over a week almost nonstop with no damage. Perfect! Plus they look cute and the stoppers work pretty well!

Good for costume/cosplay or decoration
Super cute. Great for costume or decoration. Glass is not thick like pyrex or anything. Rubber cork is a nice touch.

Great Flasks, Passable Stoppers
The glass is amazing, both thick and well made. Size is consistent, graduations are correct, and they could pass for genuine American borosilicate. Stoppers are iffy. I’ve had leaks from them, mostly when I open the flasks, and they seem to retain the liquid around the edges of the stopper. That said, they’re perfectly airtight. Great value for the set, and I appreciate the muted look of this brand. Nothing crazy, and they actually do mark the flasks, but it’s not overboard.

Essential oil Blending
I am creating m own blends of essential oils. These little flasks are perfect for small batch blending.
