History for Diamine Inkvent 2021 Brandy Snap

Brandy Snap is an ink that came for day 21 of Diamine's Inkvent 2021 calendar, in a 12 ml plastic bottle. It has since been released in the four-legged glass bottles that hold 50 ml.
The ink is caramel-brown coloured, with plenty of shading but without becoming hard to read. It can appear more amber or more brown depending on paper and amount. As with nearly all Diamine standard inks, the general consensus is that it is well behaved.
