Delta Papuasi is a part of Delta's Indigenous Peoples collection; the series commemorate the existences of aborigines' inhabitants of New Guinea - Asaro Mudmen. They have been residing in the forests of New Guinea for thousands of years but they were only identified in the year 1980. They used to cover their body with mud to drive away enemies and vile spirits. To replicate their impeccable appearance, Delta have introduced the white-grey-beige resin which appears as the dry mud and the black and brown which resembles with the dark skin of the Astro Mudmen. On the cap, there are two black and white rings that represent the flag of New Guinea. The series is available in fountain, ballpoint and rollerball versions.
