OCB activated carbon filter conical 6mm

25 pieces ultra-thin 6mm OCB® roll-in filters with activated carbon in conical shape.

Anyone who likes to roll nice cones knows the problem! The filters are often too thin at the top and slip out easily.
Whereas you could still help yourself with classic paper filters by tinkering, there was no solution in sight for ready-made activated carbon filters until now.

Until now: OCB® has taken pity on us and has now brought out these practical roll-in filters in cone form.
The filters are 6mm thick at the bottom, can be used several times and have an optimal draw resistance.
