This is only the top of the case, and has a key-ring hole for the included keyring. It is available separately for people who want to mix colors.
Top of case only. This will not work with older cases. Look for the “teeth” on the mating surfaces.
Colors are approximate due to variations in monitors and lighting. Sometimes the translucent greenish-blue looks more bluish or more greenish. The orangish amber looks a lot like an automobile tail-light color in person.
