The Pilot Custom 823 is a vacuum filler in an elegant and simple design. It's a very good writer because of the gorgeous 14K nib. 

This fountain pen comes with a nice gift box & an ink bottle (70ml) which is shown on the photos and has a 14K nib. You can choose between the sizes F (fine), M (medium) or B (broad).
