Superb quality! Much better than any other test tubes I have found. Thick and strong glass. The packaging was perfect and safe. Not one of the 100 tubes arrived damaged. So happy to have found a Canadian supplier that ships QUICK!

— Indigo: Thank you for kind review and continued business.
We have ordered a bunch of these for craft projects. They always arrive quickly and are well packed to avoid damage by the shipper. As mentioned in description they can vary slightly in diameter but length is pretty much always accurate. The lip can also vary between orders. Overall very happy with Indigo Instruments and would definitely recommend.

Great quality, very quick delivery, using for a test tube vase so I wish there was a bit of a wider lip on them.

Good price, quality seems decent. Packing was done well so I received no cracked/chipped/broken test tubes.
