I can’t comment on the use of these as genuine scientific glassware as I bought them for the express purpose of displaying two of my passions; science (especially chemistry) and gaming. Other options may be available, but the range of sizes are ideal, allowing display of different items (so far spare meeples, dice and Lego mini figures). My only minor disappointment was that they didn’t come with bungs, which I had to order elsewhere.

    The arrived quickly and were as described. My girlfriend was using them to make her own face creams. They take the heat from that fine. The only thing is very difficult to clean because of the shape. But that’s really more of our problem. Recommended.

    Excellent idea as a mini wine decanter. Saw them at a restaurant and had to have them!!! A nice addition to any wine drinker! Since they are “design for heavy lab usage”, they are sturdy and last forever!

    I've used a lot of budget lab glassware, some good others well you get what you paid for. This is the first time I have ULAB products and I am very impressed at the uniform and solid quality of the flasks I received. The listing description was informative and accurate. The packaging second to none. I can not speak for long term use as I have only used for a few days collecting and boiling out solvents. They are made of slightly thicker glass than other previous brands I've owned. I also do not take time to write reviews but was so pleased with the flasks and what I got for the money, I wanted to say thanks.
    Cheers
