These stainless steel Lamy nibs are suitable for Lamy AL-Star, Safari and Joy fountain pens (all available online here) and various other Lamy models.
You can buy the nibs loose and just swop them out with the existing nib on your Lamy pen..
If you order a Lamy fountain pen from me on this shop then you are able to order it with the nib of your choice - just add it to the notes section when you order online, or whatsapp Robyn on 076 235 6563
