Copper tape has countless applications in electronics from creating low-profile traces for electrical components to RF-shielding and antenna-making. Copper tape is even used to join things together using solder, like the stained glass on Tiffany lamps.
This copper tape is backed by a conductive adhesive, is 5mm wide and comes in rolls of 50 feet. Perfect for more precise projects.
The 5mm copper tape is a great option for making paper circuit traces. It's a better option compared to using the 2" copper tape. Here's an example from the Light Up Valentine Cards tutorial:

The project I used this for was a partial success. Making consistently working connections was tricky and finicky. It worked eventually but it took many tries.
My students were able to build circuits with the conductive tape. However the tape would crinkle easily and once it crinkled it would not work as expected.
I’ve used this tape with my students for the past 4 years to make a light up Valentine card. It’s great!!
