Syo-ro (dew on pine tree), by Iroshizuku. A beautiful teal colored ink that leans a lot more towards green than towards blue. A very versatile color. Suited for note taking in the office, for personal notes, for writing and for personal correspondence.
No feathering, beautiful shading, not too wet, writes smoothly. Drying time on Crown Mill was surprisingly fast with 23 seconds, as is its ability to withstand a few drops of water.
This ink, as almost all Iroshizuku inks, is a dream to write with, provided you use it on quality paper. Using Iroshizuku on lowest bidder paper is blasphemy and punishment will be severe and swift. Use it on it Rhodia, Crown Mill, Leuchtturm, Tomoe or the likes, and you will be reward equally.
Comparing the ink to others is not so easy. The differences between colors that I considered close cousins, are bigger than expected. Ku-jaku is a teal that leans far more to blue, moss green (Graf von Faber Castell) is darker and a lot greener and Emeraude de Chivor is more blue as well.
All in all, this is an excellent ink and highly recommended. It's one of the inks I come back to often.
