Not bad. Wished they were a bit larger and the glass is pretty thin but does the job. Definitely like the cardboard for storing and keeping safe.

Bought this set to help my child with a summer science fair presentation that involved raising several queen ants and placing them in different conditions to see how they would adapt/survive/or not survive and how the conditions would affect growth of the ant colonies. Won 3rd place if anyone cares, LOL. But I digress, the tubes were very clear and perfect for presentation and had no issues with any of them breaking/shattering. My wife used the leftovers as tiny hanging vases that grow succulents in our south dining room window. Good overall product for what they were used for.

Good quality little test tubes. But be warned.. they are VERY small. You can only use the MINI m&m's if you are planning to fill them with candy, but they do look great and make a fun goody bag filler for a science themed kids party!
