AgIC Silver Ink Maker is a silver ink pen, used to draw circuits without using PCB boards. The advantage of using this type of pen is that we can use a variety of materials to make electrical circuits, including on paper, plastic covers and because painting with silver is not limited to the size of the circuit.
