AgIC circuit markers allow you to draw circuits as you want. No wiring or soldering required. You can also use the circuit correction pen to fix the circuit. Great for introduction to education and crafts. For easy circuitry and fun, use the "AgIC LED & Battery Set" (sold separately) or "AgIC Circuit Sticker" with LED ready to apply. By attaching batteries or LEDs to circuits with cellophane tape, anyone can start making electronic circuits. This marker does not generate conductivity normally on regular paper and can only be used on special paper or some inkjet printer photographic glossy paper. Please note that some glossy paper does not demonstrate conductivity.
