A collaboration with Lawson stores and Osamu Tezuka World in April 2015 brought these bottle caps featuring 15 Tezuka characters. The caps came free with a purchase of Suntory 500ml bottle products, and were attached to the neck of a bottle in a blind bag. Characters available were Atom A, Atom B, Uran, Ochanomizu, Higeoyaji, Hyoutantsugi, Phoenix, Sapphire, Tink, Black Jack, Pinoko, Leo A, Leo B, Lyre, and Unico.
