The readil problem is that the two smallest rubber stoppers simply fall into their flasks and ate totally unusable for anything.Glassware is ok but I bought the one with stoppers so I could use them. I cannot.Good value, good product otherwise. ### ⭐ Buyer Beware! 4 out of 5 flasks contained imperfections or chips inside the flasks. *by A***R on Reviewed in the United States on July 9, 2019* I use flasks while making herbal tinctures. These flasks would not hold up to even a low hotplate. Very disappointed after seeing all the good reviews. Now I will have to drive 40 miles to UPS because they don't pick up from my location. Thanks for wasting a bunch of my time and money, Karter Scientific. ### ⭐⭐⭐⭐ Art Project Materials *by B***S on Reviewed in the United States on August 23, 2019* While I do think these were a great value, the rim on the one I chose to work with (150mL, wasn't sure what size I would need) just basically exploded. And that is a figure of speech I'm using, I'm not doing science with these, it just popped off all around the rim while taking it out of the box while inspecting them. For my purpose, an art project, it's fine, and luckily the rim doesn't even matter for the project.However, if kids were involved or if my aesthetics had dictated the rim needed to be shown I might be saltier about the sharp edges left. My project involves wrapping the top of the glass with wire and it broke BEFORE the glass came into contact with any metal, which I thought was ironic.Now if the rest of the flask's rims also shatter for no reason, I might come back and change my rating but otherwise I'm willing to just accept that that one had a flaw in it. (Maybe sudden drastic temp change bringing it from outside to inside caused the fracture? Idk.)
