Second order; they seem to be as advertised.
My first order was in early 2021; the items appear identical across this one year time frame.The product appears to be as advertised. Based on a visual inspection of the glass it appears to be reasonably thick borosilicate glass.My use case is storing premeasured doses of aquarium dechlorinator in ambient household temperatures. It works well for this purpose and the cap seems sealed enough to prevent evaporation.

Great value
I use these to store beer yeast and these 25ml tubes with screw cap are just about perfect for this. I just ordered some more. The yeast stays good for a long time. The caps are airtight and do not leak any of the fluid. I use a sharpie to write on the glass what the contents are and the date of storage. After I use the yeast I clean and sanitize the tube and cap, clean the marker off with alcohol and I can reuse.

Perfect
They came without any cracks and was nicely packaged. They can store a bit more than 30 ml. In the picture, both of the tubes have 30 ml water in them. Even with vigorous shaking, there is no leakage. All of them stood by themselves without wobbling. When screwing on and off the caps, it didn't feel like it would break from the force. All in all, extremely satisfied.

Pretty handy and convenient way to pre-measure oil for two-stroke engines.
These test tubes have secure caps and are the perfect size for containing the proper amount of oil to mix with gasoline for two-stroke engines.

Careful of cracks.
I liked the sample tubes but three of them had cracks in the glass where the caps screw on.

High quality glass tubes with great lids
I bought these tubes to hold powdered, crushed pill medication. The glass tubes are smooth and perfect and the lids are the best - easy to use, they provide an excellent seal.

High Quality Product
I use them mostly for collecting sand and dirt during my road trips and then do the trick. They are suitable for liquids as well as they seal quite well. Overall, a high quality product, and would definitely buy again.
