How to use

Select a pen in the desired color and remove the cap or click the tip if applicable. Apply moderate pressure for continuous ink flow and write or draw as needed. For best results, close the cap or retract the tip after use to prevent drying. Use different colors to organize notes, emphasize text or layer simple sketches; allow ink to dry briefly on glossy surfaces to avoid smudging.

Usage recommendations

Store the pens horizontally or tip-down to maintain consistent ink delivery. Keep them capped when not in use and avoid prolonged exposure to high temperatures or direct sunlight to preserve ink performance.
