Ink Bottle Features
Design detail 1
The evocative form looks as though a drop of molten glass has solidified. Filling the bottle with ink creates the illusion of two elements becoming one. The stable base prevents the bottle from tipping over easily.
Design detail 2
The generous 20mm opening with an 8-degree angle makes dipping easy without damaging delicate nibs. The shallow depth allows for effortless refilling of converters and helps to keep your pen clean from unwanted ink.
Design detail 3
The palm-sized 35ml bottle can be easily picked up and shaken.
Our pigment inks have been developed in an ongoing partnership with Japanese colour specialists Turner Colour Works. The inks are designed to minimize clogging in nibs while also being water and bleed resistant.
In a convenient 35ml bottle, suitable for several years of daily use.
Fade and smudge resistant, even in the rain. For words that stand the test of time.
Dry ink on nibs can be removed using our cleaning solution.
