1. An ink device for a writing instrument having a barrel, the ink device being configured to be enclosed within the barrel, the ink device comprising:
(a) two or more ink cartridges, each of the ink cartridges containing ink; each of the ink cartridges having a proximal end and an opposite distal end; and
(b) two or more nibs, each nib connected to the proximal end of said two or more ink cartridges,
wherein a proximal end of one or more nibs is angled such that, when placed within the barrel of the writing instrument, a plane formed by the proximal ends of the nibs is substantially parallel to the surface of a substrate when the writing instrument is held at an angle of 30 to 150 degrees relative to the surface of the substrate, and
wherein the ink device is configured such that, when placed within the barrel of the writing instrument, the plurality of nibs are disposed radially around a center nib and extend through a proximal end of the barrel and transfer the ink from the cartridges to a substrate contemporaneously, providing a discernible effect of two or more characteristics.
