History for Diamine Inkvent 2019 Mulled Wine

Mulled Wine was first released in a round 7 ml glass bottle through the Inkvent 2019 calendar. It is now available in the 50 ml, four-pronged glass bottles of the Blue collection.
The ink has been called dark maroon, or rich, purple scarlet; it lives up to its name being "wine red".  There is some shading, but nothing overwhelming, and no sheen has been observed.
