## Customer Reviews

### ⭐⭐⭐⭐⭐ fantastic product
*by W***  on 17 February 2025*

Fantastic dint not realise they was made out of glass so now i realise why they bit on expensive side but I'm absolutely pleased with the product very well made and none was broken which is a bonus definitely worth paying the price for what they are api products are the best

### ⭐⭐⭐⭐⭐ fantastic
*by A***S on 30 July 2021*

after trying to take the cap off a test tube and taking most of the tube with it a got this replacement pack and it’s absolutely fab. the caps aren’t as tight (but still a perfect seal) so i’m not as worried about them breaking the test tubes as i try to get them open.

### ⭐⭐⭐⭐⭐ Great find
*by T***E on 24 July 2021*

Am extremely accident-prone, so am forever dropping and mashing these test tubes. The 24-pack is a great find, will hopefully last for a while.
