J. Herbin is a french company which makes fountain pen inks among many other fining writing related products. I got this ink from Overjoyed for about SGD$14. This is a bright purple ink that is slightly too saturated for my everyday use. The dry time on my old review paper (Muji notebook) is excellent but it is just regular on the new review paper (Kokuyo loose leaf). There is some shading visible on the wider nib sizes. There is no show through or bleed through.
