Pressure bar for button-filler pens
To get your button-fill pen (Duofold, Waltham) to fill well, the pressure bar has to work. Having the right length is a necessity. This bar improves the function of every pen I've used it in. Continuing to use the original pressure bar may seem right, but the metal declines over time and won't fill the pen properly. Anderson Pens provides the parts I require to keep my pens working right.
