30ml bottle of Blackstone Ink from their "Colours of Australia" collection.
Blackstone Golden Wattle is a golden yellow ink inspired by the flowers of the Golden Wattle (Acacia Pycnantha). The golden wattle is Australia's Floral Emblem and is an Australian native tree that grows to about 8m in height. From late winter to early summer the trees are completely covered with their bright golden yellow flowers. It's well behaved ink and on some papers with broad nibs or a wet pen it will show interesting dark orange halo effects but like many yellow inks it may crystallize on some nibs. This is completely harmless and can be wiped off easily
