Doodlers of all ages the idea of discovering art. Creating with double outline markers is both inspiring and infinitely relaxing. The perfect way to relax! Dual markers work best on white paper (especially heavier base paper), but customers like to experiment with different surfaces (glass, , fabric, etc.). When in doubt, try it! Ink bleeds from the paper, so it's best to add an extra layer behind what you're scribbling. Outline markings are permanent. When finished doodling, or if possible, cover immediately and store horizontally. Product Description: Before using tags: Each marker (turn on!) Press the nib into the paper and pump until the ink runs out Once the nib is completely saturated with ink, the marker is to use! Product includes: 8 pens
