Packing: 12 per box Unit price refers to the price of one piece.

Usage: Can be written on any surface, including metal, glass, wood, stone, plastic, paper, etc., with a wide range of applications.

Features: Special fiber tip for smooth and fluid writing, exceptional coverage, a wide range of colors, and no fading.

Instructions for Use: Shake the pen several times before use. Hold the pen with the tip facing up, and press the thumb several times to release the air within the pen barrel. Then, press the tip of the pen lightly on the paper a few times until ink seeps out of the tip. Once the ink is evenly distributed, you can begin writing. After writing, make sure to cover the cap tightly to prevent the ink from evaporating.

Please read the instructions carefully before using for the first time.

1: Before use, shake the pen body up and down several times to ensure that the ink inside is well mixed.

2: Open the pen cap, hold the pen upright, with the tip pointing up, press the tip for about 3-4 seconds, then release your hand to allow the air in the pen tube to escape (new pens are completely sealed, and there is a lot of air in the tube. Too much pressure can cause ink to spray out when using it).

3: Press the pen tip down several times until ink seeps out, and it can be used. Note that you must use up the ink that comes out (when the ink becomes lighter) before pressing again, to prevent too much ink from seeping out.

4: After writing, please tighten the cap tightly, and repeat the first method when using it again.

When the pen is not in use, cover the cap and place the pen head down vertically to prevent the color from changing (the paint will settle) for the next time you use it.
