Every aspect of refilling your fountain pen has been considered with Lamy T51 30ml bottled black ink. A stable, wide bottomed jar helps stop tipping and prevent spills. The bottle's interior is cone shaped, forming a collecting basin or well, which assists in getting more ink out of the bottle and into the pen.
