These are very cheap hemostats. I have had my other pair of hemorats (made by a different company) for 10 years and never had it pop open. These are not only super light but the joint on these is very weak and they have frequently popped open while I have been fire cupping... terrifying.... luckly, I caught it each time. But it has happened enough times, I am retiring these after just 6 weeks of use and will purchase a different pair.

Advantages: none, I have to buy a new pair when I just bought these.

Disadvantages: very cheaply made and doesnt hold cotton balls securely!!!! These are accidents waiting to happen.
