Copper Foil Tape 8mm x 30m with non-Conductive Adhesive
Great for use with Chibitronics Circuit Stickers and suitable for any other application in place of regular wires. Also useful for EMI shielding. We've found the 8mm width to be perfect for kids – wide enough to resist accidental tearing, yet still narrow enough to create curved paths easily.
The adhesive is not conductive, so you will need to fold the ends of the tape to make a secure electrical connection when you need to join two tracks of copper tape together. A version with conductive adhesive is available here.
