SNS bottles, also called bullets due to their shape, are used for dosing powdery substances such as snuff, etc.
How the dosers work
The upper plastic cap is equipped with a rotary valve. This is locked as soon as you turn it down. Turn the bottle upside down and open the valve. The powder glides into the acrylic part. Close the valve and return the SNS bottle to its initial position. Now you have just the right amount of snuff.
