Product Description This is a replacement pump head specifically designed for cotton. When you press cotton against the top, the lotion will soak in. There's no need to open and close a cap, allowing for one-handed pushing and quick skincare. Instructions for Use Please cut the tube to match the size of your bottle. When using, turn the top plate to the right until you hear a click to unlock it, and then press down with cotton or similar material to soak it with the liquid. A single push dispenses approximately 0.5cc. ◎ Tube Length Guidelines ● For a 400ml bottle, you can use it without cutting. ● For other bottle sizes, cut the tube to a length that is the height of the bottle's shoulder minus 4cm. ● The appropriate length is when the tip of the tube aligns with the corner of the bottom of the bottle. Precautions for Use ● Pressing directly on the top plate may cause the liquid to spill out. ● When not in use, please use the included cap to prevent dirt. ● Excessive pressure may cause damage. ◎ Notes for Cutting the Tube ● Replace the tube in a clean state free from dirt or dust. ● Ensure the tip of the tube is attached properly to prevent it
