Using these Schmere Sticks is super easy. Just grab a stick and start coloring on your clothing, costumes, shoes or any other suitable surface. You'll see the color appear right away. When you're done using them, don't worry about stains because they're completely washable. Simply throw the colored item in the washing machine and the color will come out. As for storage, keep them in a cool, dry place. Make sure to keep the caps on tightly so the crayons don't dry out. Also, when using them on fabrics, it's a good idea to test a small, hidden area first to make sure the color behaves as expected.
