Pokémon | Poké Ball | Pop-Up Figure | Pikachu

These pokeballs open and close by simply pulling from the top and bottom - the button is purely decorative :) 

Also please note that this will come as pictured - a single pokéball, not enclosed in a box.

Poké Balls are spherical devices used by Pokémon Trainers to catch wild Pokémon or store their own Pokémon. There are many types of Poké Balls, the most common and basic of which is the namesake red and white type.

Poké Balls are arguably the most distinctive symbol of the Pokémon franchise. In the Pokémon World, it is common to find references to Poké Balls, such as battle arenas bearing the circular shape of a Poké Ball or them being a decorative element on walls and floors. Even some Pokémon bear the shape or design of a Poké Ball, such as Voltorb, Foongus and their respective evolutions.
