This is the product of miracles!  even the biggest wounds can close in seconds!
Method of use:
First disinfect the wound with alcohol and then put a drop of the blood stopper and clean the wound gently with a wooden stick. If the wound is deeper, wait a few seconds to do this.
After the blood has stopped, you will have to clean the nail plate very well, hindsight this will cause liftings for any product applied later!
