Using these water reveal pads is super easy. First, fill the chunky water pen with water. Then, use the pen to color on the white pages with line drawings. As you wet the pages, beautiful colors will show up. When you're done, let the pages dry, and they'll go back to white, ready to be colored again. For the pen, make sure to clean it regularly to keep it working well. When traveling, you can just throw these pads in your bag because of their compact design. Don't forget to keep the pen capped when not in use to prevent water from leaking.
