This disc is hard to find, especially in clear. The Prototype Insanity was one of the earlier prism rimmed gyros made. I have 2 and have thrown the other one. This was bought as a backup and has spent it's whole life on the shelf. Clear flight plate with clear orange rim. The Prototype stamp is double foil black and rainbow laser Holo foil. If I remember correctly, it's 172g. You can see a ghost image of where my name was in ultra fine sharpie but it's hardly noticeable.
