The original bullet for all you can snuff. Fill the substance into the bottom part. Then screw the acrylic top onto the vial. There is a revolving valve at the top part, which is locked if you turn it downward. Turn the Snorter upside down and open the valve. The substance slides into the upper part. Close the valve again and turn the Snorter Bottle back into the basic position. Now you have the right amount ready to snuff.
