A Cherish Ball (プレジャスボール, Precious Ball) is a rare Poké Ball only able to be obtained through receiving a Pokémon through means of an Event. As such, this Poké Ball can never be used to catch a Pokémon unless through a cheating device, such as Action Replay. A Cherish Ball can also come with a Pokémon over WiFi in Pokémon Black and White.
1x during all encounters.
This is the first Pokéball to have a much less circular shape than the rest.
