Gelly Roll Stardust contains an inert cosmetic grade finely ground
glass powder that produces a wonderful shimmery brilliance. On light
colours it shows up as colour and sparkle, on dark colours the sparkle
shines through. A roller ball pen that is easy and comfortable to write
with, a 1.0mm ball gives a consistent 0.5mm line. Works well on glossy
and matte paper. Non toxic.
