@moey2720 It's simply a powder based product I purchased on Amazon in case the need arose for that "accident" we never expect to happen. There are different brand names but I purchased "BleedStop" because of price and what I though would be useful. It's basically a powder in a packet that you can rip open and apply to the wound while applying pressure. Have only used it once while in the workshop and not really a major cut but just to see how to use it and it did form a clotting or stop of blood flow fairly quickly. I think it was around $15 - 20 for a small 4 packet kit. Guess the main thing is it worked as compared to just a bandage. have 2 packets in the car and the rest at home.
