Exotic sonokeling wood from Indonesia is botanically identical to Indian rosewood. It is known for its hardness (the darker the wood, the harder it is) combined with suppleness. This combination makes it ideal for calligraphy nibs.
Sonokeling nib lasts for extended period of use without any need to sharpen.
This set contains 5 pens in sizes 11, 12, 13, 14 and 15 mm.
