(hex:B0) (Red) and (hex:B0) (Blue) are glitch items in Pokémon Red and Blue.

Attempting to use one of these glitch items from both in and outside of battle may result in Professor Oak's message that the item is unusable. Despite having the name JACK in Red, neither of these glitch items are 'Jack' effect (also known as Rival's effect) glitch items.
