The seven Apricorns

Apricorns (ぼんぐりのみ, Bonguri Fruit) are nuts that grow on trees in the Johto region. They are picked like Berries, but used to create new Poké Balls. Kurt, a Poké Ball smith who lives in Azalea Town, can make each Apricorn into a different kinds of Poké Ball which is unavailable elsewhere in the Pokémon world.
