Walnuts in Papua New Guinea are yellow-brown or reddish-brown, with straight or staggered textures and beautiful waves, often with gray or black stripes. At the same time, the surface of walnut in Papua New Guinea has golden stripes, which are very similar to nanmu, and it is the only wood with golden effect except nanmu.

Simba walnut has uniform texture, heavy weight, high hardness and moderate shrinkage. Easy processing, good planing quality, strong paint adhesion, good nail holding power, slight corrosion resistance and good drying performance. Suitable for high-grade furniture, floors, kitchen cabinets, jewelry boxes, wood carvings and handicrafts. The density of this kind of wood is close to that of mahogany, and there are few species, so many domestic customers use and collect it as mahogany furniture. (and the second half-hour economic column of the Central Committee, No.2013 1024, reported that this kind of wood may be included in the category of mahogany in the future).
