The ink is oil-based, so even if you use a water-based marker to paint over the stamp, the ink won't bleed.
Use it on notebooks, diaries, sticky notes, etc., and color it to your liking to decorate them. If you're using a planner or notebook where you also write on the back, we recommend not using too much ink.
