This is probably not advised for professional scientists looking for rugged, sterilized sample vials, but they work wonderfully for everything from party favors to collecting scientific samples when a large number of samples is needed. Keep in mind that these are plastic, not glass, and thus should be handled accordingly (no steam cleaning, etc.).

I ordered these to be able to organize my beads for my diamond painting. Tops are a cork style, and stay in real well. The tubes are 3in long and not real big around but they don't need to be big for my tiny beads. I do kinda wish they were longer but I'm very happy. Thank you Amazon and teenitor

I use these for holding spices in my knife bag. The slim size allows me to fit plenty of my specialty spices and salts that we don't use in menu recipes but have come in handy for off menu requests. I do wish the caps fit tighter as fine powdery spices and liquids can slip out. Otherwise, love them

The test tubes and caps are well made and OK. However, what I didn't know is that the diameter of the tubes narrows as you go from the top down. The bottom of the tube is not as wide as the top. Because of this I couldn't use them for my intended purpose. However, I kept the tubes because they were inexpensive and because I thought I might be able to find a use for them

It’s also a handy ashtray/snuffer. It’s perfect for carrying joints rolled with a 70mm hand machine. Of course it also helps contain telltale aromas while keeping the reefer from drying out anytime soon. Fifty test tubes hold almost exactly an ounce of machine/hand-rolled weed using 8x18mm pre-rolled tips. A joint in a test tube makes a nice little gift, too. Of course they can be reused. Pull the blue plastic plugs straight out with a twist instead of pushing them out from the side & the tubes will not crack near the top. I’m still using the most of the first 50 I bought a few years ago.

I purchased these to replace the glass tubes that come with the water testing kit from API. I've owned aquatic pets for several years now, and I wish I had bought these sooner. Not only did I break the original set of glass tubes that came with the kit, but I also broke three of the API replacement tubes that I ordered as well. These tubes are plastic and very durable. I have been collecting the water using the measurement on the API tube and then pouring it into the plastic tube before mixing in the chemicals. You can eliminate this extra step by marking the plastic tubes with a permanent marker. I haven't dropped the plastic tubes (yet) but judging by their material, they would not shatter.
