Bureau Direct (London, England) First place that I bought ink and pens. Really speedy service and lovely people to deal with.
Diamine Inks Gorgeous. Also glittery in places. More colours than you will ever know what to do with! Made in the UK.
Pure Pens (Newport, Wales) Ordered one day and it arrived with me the very next day. Wales to a Scottish island in less than 24 hours! Brilliant!
Cult Pens For a start they seem to be holding the full range of Robert Oster inks, which is BRILLIANT.
