It’s an o-ring. It does what it’s supposed to and is accurate to size. Helped me out on a project.

*by T***C on Reviewed in the United States on April 16, 2019*

The product was exactly what I wanted, I did not need 100 but price was reasonable, I could not find the exact size locally from anyone.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    They're O-Rings
  

*by S***A on Reviewed in the United States on May 30, 2017*

They do what O-Rings do.They're pretty rubberyI guess the one defining feature is that they're not dried out or in any sort of bad condition.It'd be pretty hard to mess up rubber circles.
