>>9403888>The Headmasters Dinosaur cassette combiners were HUGE holy grails for a long time (the only cassettes not released in US) but Hasbro recently paid to have the molds re-created and released all of them and released them in the US.Unfortunately those releases were super hard to get, packed in with overpriced garbage Bumblebee repaints, con/pulse exclusives, lost in transit from China, etc...
And then to add insult to injury, they were really poor quality. They barely hold together correctly, only charitably stay in tape mode, and many of them were misassembled at the factory.
The old KO G1 Repro dinocassettes that came out of China about 10 years ago were actually quite good, and infinitely preferable.
