Disappearing Spy Paper Dissolving Note Pad Letter Head
This "spy paper" looks like ordinary paper, but is unique in that it dissolves in just seconds when contacted with liquid, resulting in a useless, non-reconstructible mulch which is far more secure than the output of any standard shredder. You can write on this paper normally, but contact it with any liquid, even saliva, and it transforms into a secure mulch. It's ideal for those confidential notes that may have to "disappear" quickly with little advance notice.
