Sennelier Indian Ink A la Pagode Black 30ML – Ideal for Detailed Ink Drawings, Calligraphy, and Mixed Media on Smooth Papers with Intense Black Pigment.

This is a great waterproof shellac based ink - suitable for dip pens and brushes. This is NOT for fountain pens. With that out of the way, this is superb, jet black, with a smooth sheen when dry, no feathering, totally waterproof and capable of the fine hairlines. Off course it dries out to form residues on the dip nib, but then like any dip pen user you just wipe it off with a rag, preferably with a few drops of alcohol. I tried to get a 250ml and couldn't. Pity.

Good intensity, at first rather good experience, totally waterproof but after a couple of uses I found my nibs were getting clogged so badly they weren't moving. The bottle was getting deposits at the brim like thick salty flakes.
