You are looking for a small container with a screw top. It is near to a busy roundabout although the foot paths are wide and clear and there are multiple crossing points near by allow access from all directions. If you have children then please keep an eye on them.
As this is a busy area some stealth will be required. We don't want those muggles spoiling things !
There are plently of spots to park nearby that allow for a short walk of a just a few minutes. Please don't park next to the cache and attempt this as a cache and dash.
