- Wednesday, March 27, 2013Good test tubeReviewed By: Jack
The quality is excellent for homeschool, the price is very reasonable, and the packing was done well so that none broke during shipping. I haven't heated them so I don't know how they will stand up to a flame. Shipping was faster than I expected. HST's does an excellent job!

These test tubes are great quality. The one thing I was dissatisfied with was the size. I know I should have checked out the metric size myself, but the "large" test tube I ordered was not as large as I expected. Order these for sure...just make sure you know what size you are getting.
