A devious one vying for the prestigious tiltle 'smallest writable cache' - in these parts, at least. Made to measure.
This cache is sub-nano, well hidden, but accesible, and waiting for the observant to find.
You'll need a pair of sharp tweezers or a pin to extricate the log sheet. Putting it back can be a challenge to but just keep rolling 'til it fits - should take less time than the find.
Enjoy 🙂
