The test tubes were exactly what I was looking for. I agree with Doug - they were packaged very well and no damage occurred during shipping. And they were shipped immediately and arrived in a very short time frame.

Test tubes were very well packaged and arrived in perfect condition. I appreciate that they did not have any markings since they are to be used as vases.

Good to hear they got there ok & you're happy with their having no markings. We realized years ago that the esthetics demanded they be completely blank.

Test tubes were exactly as described. Appreciate the fact that they do not have any markings on them as they are used as vases.

We've ordered without markings for years for that reason. Most sources only offer this in disposable soda lime glass culture tubes that break easily.

The durability of lab glass is essential to making quality horticulture display stands that last. Bulk pricing made the test tubes very affordable and the cost of the overall project minimal. Competitively priced and shipped promptly. I purchase all my lab glass from Indigo!
