Description

Our flagship conductive ink pen now comes alone! Use it on any surface a rollerball pen will write on. The Circuit Scribe can draw 60-200 meters. 60 meters is seen on surfaces similar to a napkin, and 200+ meters on photo paper. Pen erases on photo paper by scratching the ink away, and is also the most conductive on this surface (<2 ohms/cm). Soldering is also possible but tricky, and greatly dependent on paper/surface type and solder type.
