“I bought this to use with the Circuit Stickers Starter Kit. The kits itself was not in stock so I ordered some of the items separately and found the book online. This copper tape is a little thinner than the one recommended in the book but it still worked fine. My children (7 and 9 years old) were able to use the copper tape on their own to complete the first few projects in the book. Great child friendly way for kids to have a hands on experience with the world of circuits.”
