Finally, a standard Aussie-size cone in glass! Hands up who's sick of giant glass cone pieces??? We heard ya, and that's why we had them made smaller to suit the regular everyday billy smoker.Rather than the big deep glass cones which require either a jet lighter or a love of burnt thumbs from trying to get the Bic flame in there, this great bowl shaped glass cone is the perfect size for a quick one cone sesh. And unlike other glass cones, this one has a regular sized hole, not a big one that sucks all your herb into the vortex.Fits stems & bongs with 14mm female connection.Full height: 50mmJoint: 14mm maleCone diameter: 20mmCone depth: 12mm
