Pennonia is a Romanian pen store and they (though it’s just one person, Matt, running it all!) also have their own inks they make. I reviewed (in a mini review) their glade-green Tisztás ink on my Instagram not too long ago.

Matt was kind enough to send me some inks to try and review. The one I was initially most interested in was Vízláng (‘Waterflame’), a permanent blue with lovely sheen. But when I saw this unique ink I knew I had to review it first!
