For many years now I have used Staedtler Lumicolor 319 Special F pens for plant tags. They are finer than most allowing more detail on mall tags and last for years. They can be found on Ebay and most good stationery stores. https://staedtler.com/au/en/… rmanent-special-319-permanent-special-pen-m319/ Neil Jordan Tasmania _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/…
