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.
Really great quality test tubes for what I am using them for -- replacements in a test tube vase! Arrived promptly and everything was very well packed.
I was very satisfied with the quality of the test tubes for what I'm useing them for. Packing was very well done with no damage, blister wrapped carefully. Shipping was prompt. Will definitely order from Indigo again

Great quality, timely shipping
These test tubes are consistent in size and the both the price and customer service are great. I have ordered thousands of test tubes from Indigo for my arts and crafts business in Austin and am a very happy customer.
