Share'a'Bud v2 - Cigarette Tip / Bong-Adapter

Winter time, cold time.
And when you share an herbal cigarette with friends, unfortunately you don't just share the pleasure.

My solution is quite simply a matching herbal cigarette tip, which can also be used as a blunt or joint adapter for the bong/beaker, which has a maximum opening of 15 mm.

The opening is designed for the normal prefabricated king-size cones, but has enough clearance for other filter diameters.
The cigarette in the picture is of course a fake ;)
