Sailor Fountain Pen Professional Gear Realo Black Fine Point 11-3926-220. A rotary suction fountain pen is now available as a professional gear that exudes luxury and status. Putting the tip of the pen into the ink bottle and slowly inhaling the ink as if taking a short break will bring you a calm time of healing and peace. Rotate the tail plug slowly and feel the comfort of the ink as it inhales, enjoying a tasteful and luxurious adult time of “relaxation”. The ink suction method adopted for Realo is the “rotating tail plug suction type” in which the fountain pen itself sucks ink. By rotating the tail plug, the threaded part inside the barrel moves the piston back and forth, sucking in ink. Nib: 21K gold bicolor finish, large size. Since it is a rotary suction type, suction converters and cartridge ink cannot be used. Please carefully look at product details and images before purchasing. Since things on the pictures are all, please check carefully. I can not accept complaints from later. International Buyers – Please Note.
