American Educational Borosilicate Glass Round Bottom Test Tube, 25mm OD x 200mm Length (Pack of 48)

Good product. came with 5 smashed tubes.

These are good quality tubes. My wife is using them for a crafts project to make flower vases. These are good for the purpose because they do not have printing on the galss and are completely clear. They look really nice.

Satisfactory quality of test tubes. However the wrapping conceals that 10 (10%) of our tubes were broken when the wrapping was removed. It seemed to us a packing problem rather than a tube problem. We use them for crafting where each tube is part of the price of our product so the receiving of unbroken tubes is very important to us. Thank you in advance for looking into the problem. We will look for better results this time or sadly find another source.

While the tubes were the correct size, they are not very sturdy at all. Multiple tubes were broken upon arrival leaving a mess of glass shards to watch out for. Overall quality is not impressive but if you are looking for inexpensive tubes and don't mind losing a few during shipping they will be okay.

Came in as expected, work great. I teach 7th grade accelerated science.

Just what I needed to build my spice cabinet. Thanks!

Used these to fill with bloody mary mix to make it look like viles of blood for my Halloween party several years ago.

Exactly as advertised. Everything arrived perfectly during shipment. Great for a variety of uses. I am storing spices and incense in them.
