Great combination of unique Australiana and timber. Timberbits designed the motifs with the owner of the manufacturer for his exclusive kits see Timberbits.com for his range of new release kits from Taiwon.
The Conkerberry is down to you and although familiar to me a near mystery in the US, worth a Google to understand more about this great Aussie Bush that grows so tough over a long period of time to yield amazing colours and detail. The berries are edible and these and the foliage attractive to animals, in the white ant country it grows in even the termites love it so to score good useable pieces is lots of fun and frustration.
Beaut pens.
