Get your Shimmer Markers started by giving them a shake with the cap on and then pressing down the tip into paper until the ink flows down and fills the tip.
Shimmer Markers work best on white paper (especially heavier stock paper), but customers love to experiment with different surfaces (glass, rocks, fabric,etc.).
The ink may bleed through paper, so it's best to put an extra layer behind whatever you're doodling on. Shimmer Markers are permanent.
