30pcs 20ml Glass Test Tubes 15 x 150mm with Cork Stoppers and Brush for Scientific Experiments and Plant Propagation Test Tubes

I use these test tubes to store pre-measured coffee beans. I use 15 grams of coffee beans in my Aero Press each morning. By preparing 20 test tubes of different hybrid beans at a time I save time each morning by dumping a test tube of beans into my ESP coffee grinder.

Perfect for what I needed. I used it for a baby shower party favor filled with epsom salt & lavender bath salt and put a personalized label over it.

They make cute shot glasses.One came broken but I didn’t notice until the day I had to use them.

Tubes are fantastic quality. Each tube was individually wrapped and neatly packaged. The rack was easy enough to assemble without reading the instructions. I’m happy with this purchase and would buy these glass tubes again.

Item arrived with broken pieces that almost cut my hand

Real glass, not plastic. I use these up-side-down to keep rain out of a homemade weather station's sensors such as light, temperature, and humidity transducers. They come with real corks if that is of benefit to you. For the price, these seem a bargin.

The product is just what I needed and overall was in great condition. One of the tubes was broken in shipping. I don’t want to return all of them. Can I just have one shipped?

exactly what i needed. good deal too

Showed up fast and precisely what was ordered .

good quality glass and plastic

Recently misplaced another vial I had similar to this, needed to pick up a replacement. This kit doesn't disappoint so far, though the packaging probably could/should have been a little more cautionary. Well packaged but not a large amount of packaging. Some couriers pretend the "fragile: glass" style labels are more of a suggestion

I received 30 glass test tubes with a cork stopper. The test tubes came in a box and each one was placed in bubble wrap sleeve ensuring they arrived safe and not broken. Each tube comes with a cork stopper that fits tightly but is still easy to pull off. The tubes are approximately 7.75 inches long without the cork stopper.I am very happy with this purchase and can think of so many uses for these. Perfect for party favours filled with small candy like gourmet jelly beans, party alcohol shots, rooting a plant cutting and so much more.
