The dough kit includes 7 containers of conductive dough and 1 container of white insulating dough! Each container holds 7 ounces (a normal, bought container is 5 ounces). The dough does contain gluten, but is safe and non-toxic. The conductive dough does dry out if left out of the container, but the insulating dough does not dry out.
Packaging may vary but contents are the same.
