As best I know these are vintage 1980s items. Note the obvious homage to G1 packaging, though these are not Hasbro items. Cards have some wear, some more than others. Asking $12 for a set of four, or $4 each if you want just an individual pen or two. I have four sets available, and individuals of all but the version with black head and antennae. Shipping should be $4 in the US. Happy to ship international. Thanks!
