The Eriksen Keystone filter pipe by Erik Nording, Denmark.
A cool and affordable pipe made with a hard nylon plastic stem and
shank and a quality real briar bowl which has a rubber band around the
base to give a snug and secure fit.
The filtering of the pipe is done by use of the volcanic clay
Keystones that sit under the bowl in the nylon shank. Use 10-15 stones
to give a cool and dry smoke and discard after use.
One tin of Keystones included.
Measures 150mm long with an internal bowl diameter of 19mm and depth of 32mm.
