Each Disk is manufactured from a solid brass alloy and each includes a 'spinner' mechanism, so that on a flat table one can spin each or use it in conjunction with the Golden Disk Reader.
The Golden Disk Reader is designed to easily snap into and out of the tail of Transmetal Megatron as shown. It's a very simple ball/socket mechanism, so you you can quite simply snap the pincher piece off and attach the reader. The socket portion of the reader has that 'just right' fit, into the tail piece, so it holds it's position, even with either disk inserted. And as noted, yes the disk spins along the center axis when inserted. The reader comes assembled and is a 100% original mold design of ABS plastic.
One other surprise! Each package includes a special 'tech specs' with paragraphs written about the disks and their importance, by BOB FORWARD and LARRY DiTILLIO, Co-Authors and Executive Story Editors for Beast Wars!!!
"I have the disks.
I have the power to control the future.
And the only remaining obstacle in my path to unimaginable glory, is yourself. Alone, exahausted, defeated..."
