Nice Tubes
Good product as displayed by seller. Tubes are around 4 inches in length and glass seems to be heavy duty with a nice brim, and still transparent. However, when delivered had no fragile warning on shipping box, and hardly any filler, ended up with 3 broken tubes. Besides that, good product. Definitely would recommend.

Great for aquarium water tests
I bought these after getting completely fed up with the API test tubes. These are perfect replacements for the API test kit! None of these have broken AND the caps are infinitely easier to remove. From what I can tell, the caps on these tubes don't influence the tests either (I was worried the material might change the chemical reactions). I've done side by side tests with my remaining API test tubes and I get the exact same color.Do yourself a favor and buy these if you're looking for aquarium water test tubes. They are easy to use, durable, and you'll always have spares AND you can run tests before and after water changes to see side by side results.

Only 78% survived transport. Nothing like digging through broken glass to find the survivors.
I guess the test tubes are fine, the ones that survived transit anyway.I knew from other reviews that the packaging was very poor and I was going to lose some in transit. But I was thinking like 3 or 4. Lost 11. They literally just throw them in a cardboard box, no foam or nothing. It was Armageddon in that box. The top layer was nothing but broken glass and I had to carefully pick down into the lower layers to find survivors.A moment of silence for glassware broken before its time.

Jars are good quality and tops fit and seal well
Used these to test various aquarium waters at a time. Purchased a separate rack to hold bottles.Saves a lot of time!These jars have print screened labels.The bottom line of the label measures exactly 5mlHope this helps

Exactly what I wanted, but many were broken
These were the exact size I needed, would have preferred plastic but ordered anyway. They weren’t packaged very well for glass items, 8 of 50 were broken. Still happy with my purchase for the cost and shipping was way faster than expected.
