Spica glitter pens contain archival, pigment-based ink and micro-glass flakes that make them more reflective and brilliant than the glass beads typically used other glitter pens. With a no-clog tip this pen will write shimmering color for more than 360 yards, twice the length of other writing pens. The transparent pigment can be layered over other inks to add extra color and luster. It is ideal for adding sparkle to scrapbooks, journals, art and craft projects and more.
