OVJ STEM Conductive Pen 1mm Copper

The OVJ STEM Copper Conductive Pen features a 1mm fine tip filled with copper-based conductive ink, allowing users to draw working circuits directly onto paper, cardboard, or plastic. Once the ink dries, it conducts electricity, making it possible to power LEDs, buzzers, or small motors without using wires or soldering.

This pen is especially useful in school makerspaces, where students can explore basic electronics through hands-on experimentation. It dries quickly at room temperature and provides a clean, precise way to create or repair circuits. Ideal for STEM learning, the conductive pen makes circuit design as simple as sketching.
