It is very, very tiny. You will have to look around for it as it blends in fairly well. There is no pen or pencil in this cache, as the cache container is too tiny to hold one. There is a log, but it is also tiny. And you will (probably not) have fun rolling the log up and putting it back in the cache.
My advice: Dis-combobulate the thingy before trying to counter-rotate the container bits. You may wish to take the entire gizmodic doo-dad someplace warm and un-windy to sign the log. After re-cylindrifying the log, place it into the base of the container before reversing the counter-rotation of bits. Then, and only then, should you re-combobulate the thingy in the place that you originally found it.
Got that? Good.
