This item also comes with an Israeli Bandage and emergency blanket. The Israeli Bandage comes in handy for say an injury to the torso where you can't use the tourniquet. You would use the bandage to apply pressure until you can get the person to the hospital. If the injury is on the one of the limbs you would use the tourniquet until you can get the person to the hospital.
Like I said, this is one of those things that you should have on hand, but pray that you never have to use it. If you are a camper or hiker or really anyone who does things outdoors where it may take a little bit for help to get to you, you will want to have this set in your first aid kit. It could save one's life.
You can get this item here on Amazon.
Have a great day!
