Circuit Scribe

Handy with paper, scissors, and love tinkering with electronics? Then you’re bound to appreciate Circuit Scribe. The water-based, non-toxic ink within each Circuit Scribe ballpoint pen contains silver, drawing smooth lines that conduct electricity and effectively transform sheets of paper into custom working circuit boards. It writes as naturally as any gel pen, dries instantly, and even includes optional custom components, like LED boards, a slide switch, pins for adding resistors or capacitors, motors, for a bit extra.
