## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect for all your bunging needs
  

*by A***S on Reviewed in the United Kingdom on 3 July 2024*

Like most people reading this, I didn't actually want these bungs for test tubes but for bunging holes in something else.  In my case, it's to seal the breathing holes in my kayak.  And they work great.  The material has just the right amount of squidge and the taper allows it to fit and release easily.  It's seals perfectly without getting stuck.Ideal.
