Star Unicorn Gel Pen
A gel pen uses ink in which pigment is suspended in a water-based gel. Because the ink is thick and opaque, it shows up more clearly on dark or slick surfaces than the typical inks used in ballpoint or felt tip pens. Gel pens can be used for many types of writing and illustration. Gel pen uses a gel-based ink, combining the permanence of oil-based ballpoint ink and the smooth glide of water-based ink.
