Zebra Extra Fine Brush Pen
One of the smallest brush pen tips I've tried and loved - it's firm and offers great control while writing.
The Ink is Non-Toxic, Archival (which means it doesn't fade away with time) and waterproof (so you don't need to worry about any accidental spills) .Ofcourse it's highly pigmented and I'll definitely recommend it for writing longer texts :)
