Aluminum Corp with possibility to change the tips when worn, really good feeling in hand and it's still handy for those little styluses in fact, on a smartphone when you type text with your fingers to a man better not have big paws :)!

Wacom Bamboo air to establish itself as the reference brand for this kind of lined thanks to their graphic tablets. 5/5 Amazon and Wacom.
