The cache container is small screw-top tube, held in place by magnets.
There is no room for trackables and you will need to bring your own pen or pencil to sign the log. The rule here is NO SIGNATURE … NO FIND!
This is a 'muggle-heavy' area, so the HINT is very specific, which should make this a quick and easy find.
PLEASE take care when retrieving the cache, and make sure you replace it as found. Thanks.
