If it doesn't have to be on Amazon, then I pick this Companion Cube Ice Tray for $4.99 not including shipping. How can you have your beverages chilled by anything less than a companion ice cube? Also, it could even serve as a mold for making companion cube JELLO or chocolate cubes. Damn, now I want it myself.

If you want one on Amazon, then I pick this Unicorn Keychain because it's gorgeous and has Prime shipping.
