Stipula makes a line of inks, one online shop had seven of their inks, another five. They don't seem to get much attention here on the forum. But I'm always interested in an ink named "sepia". They have big 70 ml bottles. This is my first bottle of theirs.
There are old reviews here on FPN showing an ink with this name to be a muted gray-green. That is not what the ink currently is. The online shops correctly show the ink as a red-brown. It is nearly identical to Franklin-Christoph Brown in color, but very fast drying. The pictures here didn't quite capture the reddish hue here, and often just turned it dark. Maybe if I had a more modern iPhone I'd get better color capture. Perhaps someday.
This ink washes red. It is not a replacement for PPM.
There's nothing bad about this ink, but it is very similar to all the other red-brown inks out there.
Not terribly water resistant.
