Bullet Nib：Conical nib is suitable for children’s coloring markers.
In order to make the nib soft for smooth writing feel and make it hard for high automatic assembly, bi-component design is introduced into our porous nibs. The shank of the marker nib is made of hard PE (polyethylene) and soft PE is used for the writing tip.
