Hi, I live in Belgium and am an active member of the Fountain Pens UK Facebook group (best group ever!).
I'm currently involved with #clubgrey (for grey inks) and generally learning about more inks (already at 200+ samples but there's so much more to discover...).
I also have a reasonable size collection of fountain pens (mainly at the budget end) but can't put these on Pensharing unless/until we have a Belgian chapter!
