- Reviewed in the United States on May 1, 2024These tubes are perfect for anything you need them for. The caps hit good and tubes are clear.
- Reviewed in the United States on May 3, 2024These vials are great for storing smaller bits. Just put the bits in the tubes, along with some moisture absorbing silica pellets, and placed them in my drill-bit cabinet
- Reviewed in the United States on December 22, 2019Purchased to present children with samples of magic snow they could make at home. It worked well except the lids aren't very jostle resistant and a couple came off during events. This may present a choking hazard. I have since taped them on with no further calamities. The price was right and I will be purchasing more.
- Reviewed in the United States on August 17, 2023My clever husband glued these tubes together, put a magnet on the back, and hung them on the magnetic bars we also bought on Amazon. The tubes are the perfect size for pens, screw drivers, and other small tools!

- Reviewed in the United States on October 30, 2020I purchased these to hold samples and medicine in a small battery box. They are okay, perhaps fine for their original purpose, but the caps do not secure very well at all, and the plastic of the tubes is fairly brittle, I have had two crack on me. Not something that you can really use in anything other than a stable, lab environment.
Would not recommend for anything except the lightest use.
- Reviewed in the United States on August 3, 2019These are approximately 4 inches, but the stopper goes in a little. So it's a little less than 4 inches in the center. Good quality and sturdy closure.
- Reviewed in the United States on January 4, 2022My main needs are for lab work and test tubes to be able to go through the autoclave. They hold up to high pressure for extended periods of time - I did a 2 hour test - and they are perfect, lids and all. I will be purchasing several more for my lab
