Circuit stickers are LED circuits on peel-and-stick stickers. Build circuits without soldering, plugging wires, or clips. Instead, use the stickers with conductive tapes to draw circuits on paper and other crafts. Learn to build circuits while making interactive artworks. It's easy, fun, safe and creative. This kit comes with the illustrated Circuit Sticker Sketchbook, 12 LED stickers (6 white, 2 yellow, 2 red, 2 blue), 2 coin cell batteries, 2 battery clips and one 15ft roll of copper tape.
