Izumi Pens were very excited to be mentioned in the Nanosphere's March newsletter! De Atramentis’s Heliogen Green-Copper was the star of the show as an more quirky option to a plain green ink to clebrate St Patricks day. The Nanosphere is a fantastic stationary newsletter sent out every Wednesday. It is full of new and interesting stationary products. To sign up visit their website.
