A rotatable inhalation fountain pen is created in professional gear that creates a luxurious feel and status. Simply insert the pen into the ink bottle and slowly inhaling the ink into a pause will bring you a peaceful moment of healing and peace. Enjoy a deluxe, luxurious adult "room" time while the tailplug is loosely turning and feeling comfortable as the ink is inhaled. The ink inhalation method used in the learo is a "tail plug rotary intake type" that inhales the ink by the fountain pen itself. By rotating the tail plug, the screw part inside the shaft will move back and forth and inhalate the ink.
