What’s to say about Rohrer and Klingner’s Cassia? It’s a German ink that is one of the brightest and most delightful purple inks I think I’ve ever used. I don’t use bright, purple inks extensively, but when I ink up a purple, it’s nice sometimes to get a feeling like the ink just jumps up and punches me in the eyes! That’s what Cassia does.

The dry time is about medium length, around 20 seconds or so. On Rhodia, that’s pretty reasonable, it would be faster on more absorbent paper. It’s not very water resistant, but that’s okay because it does clean out really easily out of a pen, that’s not always the case with purple inks. The shading is present but not overwhelming, it has a medium level of saturation. It does flow really nicely, towards the wet side. I like that about it :) I’m a fan of wetter writing inks!

I used a Ruby Lamy Al-Star with a medium nib for this review, mainly because it’s a popular style of pen and the nib size is a good balance between dry time and shading ability.

This ink has several others that are nearly identical, most notably the popular Noodler’s North African Violet. It’s hard not to compare these two inks, especially because NAV is water resistant. But, the leg up that Cassia has on it is cleanability (is that a word? Is now!). If you’re a fan of the NAV color but don’t want to use Noodler’s for one reason or another, then Cassia is your ticket. Likewise, if you love Cassia but want water resistance, go with NAV. Cassia is also really close to several other colors:

Cassia comes in a 50ml bottle, and is available at GouletPens.com in both bottle and sample form. I do sell this ink, so read my whole review with that in mind and use your own research and judgment to determine which inks are best for you.
