The Couple follows The Man and The Woman and welcomes The Group, due to be released in the coming months.
She tells Fashion Weekly The Group will bring the characters of the previous illustrations together in a glamorous bar type setting with luxurious gold hues.
The pieces are drawn using a specially made Mont Blanc pen, suiting Hess' personal writing style.
The same technology used to design the pen will be brought to Brisbane for a few days only in late February next year. The technology sees customers sample their writing style electronically before having a custom writing piece made in Germany.
Hess' iconic designs have international presence with the likes of Tiffany and Co, Chanel, Fendi, Dior and Michelle Obama among her extensive client list.
The evening saw guests have the opportunity to sample Mont Blanc's speciality stationary alongside the label's most recently released pieces.
The pieces will be auctioned at a later date with proceeds supporting Unicef.
