MG Chemicals Conductive Pens dispense conductive paint pigmented with either carbon, nickel, or silver. Each pigment provides a different resistivity, making each pen suitable for different applications. The valve-tip opens when pressed against a drawing surface and the flow is controlled by squeezing the barrel. These pens are designed for use on smooth, flat, hard surfaces; however, the cured traces have excellent flexibility.

All three pens are commonly used as circuit board trace repair pens; however, they are also highly useful in prototyping applications. The conductive paints contained in these pens are also available in liquid and aerosol formats.
