I found the following site called Vicker And Scrivener, while searching the internet for dip pens. Although they make glass handle dip pen holders, i.e. a dip pen, they, also, produce ink wells and inks. I noticed that they are located in Galveston, Texas (Gulf Of Mexico) and wondered about the properties of their inks and how they might compare to other permanent and waterproof inks?
