Pencil Guard for Iskn Slate

I recently purchased an ISKN Slate (2nd generation) in preparation for Inktober 2017. While the packaging for the various accessories is nice, it's not especially portable. At the same time, it's inconvenient to have to readjust the magnetic ring after having it in a back for some time.
The solution is a rubber boot that closes around the pencil and holds the ring in place. It also keeps the point of your pencil from getting dull or breaking off in transport.
