How to use

Begin by using the mechanical pencil to create initial layouts and measurements. Select the appropriate technical pen tip for the desired line weight and remove the protective cap. Hold the pen at a consistent angle and draw with steady pressure to achieve uniform lines. After use, replace the cap to prevent ink drying. Refill or replace ink cartridges according to the manufacturer's guidelines to maintain reliable ink flow.

Usage recommendations

Store the pens horizontally or with the nib facing down to promote consistent ink flow before use. Clean tips gently if ink build-up occurs and use appropriate paper weights to prevent bleed-through. For detailed work, use the 0.2 mm pen; for annotations and bolder outlines, use the 0.4 mm or 0.6 mm pens.
