Leonardo Officina Italiana ink comes in seven colours: Black Intenso, Blue Mediterraneo, Deep Purple, Green Foresta, Red Passion, Sepia Classico and Turquoise. The ink comes in a eight-sided glass 40 ml bottle. The design of the bottle is good, in that it is higher than its width. It looks good when sitting on the desk as has enough weight that it feels good in the hand. That makes it easier to fill pens with large nibs and also give you better access to ink as the overall level of ink drops.
I must say that I liked this ink as soon as starting writing with it. I like the bottle. The bottle and the cap feel very good in the hand. The style of the bottlemakes filling pens easy and although I have not gotten to the absolute bottom of the bottle yet, the higher-than-wider design is a good design quality for ink bottles.
The blue has a bold colour giving your writing a real presence on the paper. The ink has good flow. The dye-based ink has good colour and there is a bit of shading depending on the nib in use. Dry time is nicely under 10 seconds. The ink, as with most, is not waterproof. So far I have used the ink a a few different lines of pens, mostly in Leonardo pens, and therer is good performance across the board.
