As this product contains eco-friendly liquid chalk ink, it includes a small metal ball to help mix the ink. Before use (or after a period of non-use), please shake the pen both horizontally and vertically multiple times until you can clearly hear and feel the metal ball moving inside. Then, press down on the tip to allow the ink to flow smoothly. 2. If you don't hear the metal ball moving, gently tap the pen's tip-end and top-end against a desk a few times. This should help the ball move freely. 3. The pen cap features a special airtight design. Please ensure it is securely closed when not in use to prolong its lifespan. **Perpetual Calendar Links:** Phone Stand Version: https://www.pinkoi.com/product/uH7by2sF https://live.staticflickr.com/65535/51883842878_467d0b9d05_k.jpg Original Wood Box Version: https://www.pinkoi.com/product/iNgpRP2m https://live.staticflickr.com/65535/51884419340_aa60d459de_k.jpg https://youtu.be/PapDysQxDeo
