Black Pot e-pipe was designed to be as close to “classic” tobacco pipe as possible and it was my first experiment with brushed surface. The basic material I’ve used is old oak. I’ve accented the bowl with white stone ring right beneath the eGo One atomizer. The wood has black stain and brushed surface, smooth finished with carnauba wax. Black Pot e-pipe battery chamber is for one 18350 cell. This mod is not for sale. This one is heavily used by myself.
