Japan Boku-undo sumi ink stick — Shu /墨運堂朱砂墨條

1* Japan Boku-undo sumi ink stick - Shu ( orange red )

Annie’s note:
I use this for the outlines on all my orange tone sketch drawings. Waterproof once dry. Smooth, easy grinding…perfect orange-red tone.
Of course you could use it for color packing too 😽
