Copper Foil Tape wth Conductive Adhesive - 25mm thick
Adafruit
$1.85
is on back order
The tape itself is made of thin pure copper so its extremely flexible and can take on nearly any shape. You can easily solder to it, and the tape itself can carry current just like a wire. On the back is an electrically conductive adhesive. The adhesive can't carry significant current but it is very handy for sensing applications where you don't want to solder the copper tape.
