Nørding Keystone filters are highly absorbent natural volcanic clay pellets.
Keystones can be used in all types of pipes.
The Nørding Keystone filters help remove the humidity from the tobacco and the condensation created while smoking.
When using Nørding Keystones in a traditional pipe, you also “lift” the tobacco a few millimetres from the bottom of the pipe bowl, preventing the tobacco from blocking the airflow in front of the draw hole.
Lifting the tobacco from the bottom of the pipe bowl also helps the pipe smoker keep the pipe lit and at the same time offering the advantage of being able to smoke all the tobacco…
Often the remaining tobacco is usually lost and scraped out together with the ashes when finished smoking.
