Ink is made in Italy and sold by Rubinato in Treviso. Other brands of ink are made by Rubinato such as at one time some of the Colorado Pen ink.
Back in Feb 2005 - Harrogat House in Canada stocked Rubinato ink and writing accessories. I have not seen it in that many locations since that time although it is available.
