Only markings on the red pen on the tip is Fountain O Ink 5 Roll tip. On the black one all I can see is Veri smooth fine. Also made in the USA. On the barrel it has American Oil CO. The fill lever on the black one is not working. What you see is what you get so look at the pictures for description. For some reason e bay won't let me list this unless I put in a brand. THIS IS NOT ESTERBROOK. E bay put this in for me and I can't get it out.
