My thanks to Ana of The Well Appointed Desk for the ink sample.
Pen BBS is a China ink manufacturer. They have a wide variety of ink colours. No. 224 Tolstoy is a shade of green-yellow that’s just right up my alley. I’m a sucker for almost all kinds of green-yellow. I love it a whole lot. It shades super well going from a mossy green to an almost Pilot Iroshizuku Chiku-Rin light green-yellow. No. 224 Tolstoy is dry so it won’t give you the best writing experience if you filled it into a dry writer.
