Description:Ensure a dry and cool smoke with the help of NÝrding's Keystones! We recommend to use these in the Eriksen Keystone Filter pipe but you can use them in normal pipes as well. Use 10-15 in the Eriksen pipe and 5-10 in a normal pipe. These high absorbing volcanic clay pellets can be uses in any kind of pipe and will absorb excess condensation while you smoke. Just put some Keystones into the bowl and fill it with tobacco. It also gives you a better chance of smoking the entire load of tobacco as there will be no foul tasting wet tobacco in the bottom of the chamber. TAX FREE: Please note that if you are an outside EU citizen the VAT (20%) will be deducted the listed prices when/if you finish your order.
