FPR Railroad X - Ink Lubricating Additive

FPR Railroad X Ink Lubricating Additive is specially designed to lubricate dry and poor flowing fountain pen inks in order to increase flow and reduce railroading in flex pens.  For best results use 1 drop in approximately 10ml of ink.  

Railroad X can be used to increase flow in pens with any type of nib tipping but is especially designed to help maintain consistent ink flow and reduce railroading in flex nib fountain pens.

FPR Railroad X is safe to use in all inks and is non-toxic.  

Note: Some inks will require more or less than the recommended amount so we suggest experimenting with a small amount of ink before adding Railroad X to a full bottle.  Also, some inks will be more likely to feather (make lines looks fuzzy) when using Railroad X.

Product Specifications:  1oz glass bottle with convenient eyedropper cap.
