Instead, you manage your items using the following methods:
1. Key Items: Key items are special objects that have unique functions. They are usually obtained during the story and are often necessary to progress. You can't directly put them away, but you can access them through the menu.
2. Held Items: You can give specific items to your Pokémon to hold, which can affect their stats or abilities. This is done through the Pokémon summary screen.
3. Pocket Items: You can carry a limited number of consumable items like Potions, Revives, and Poke Balls. These are accessed through the bag menu.
4. Trading: You can trade certain items with other players, but this is not a primary way to "store" items.
Here's a breakdown of how to manage your items:
* Accessing your items: You can access your key items, held items, and pocket items through the Bag Menu. This can be accessed by pressing the "Start" button and selecting the "Bag" option.
* Giving Items to Pokémon: You can access the Pokémon Summary by selecting the "Pokémon" option from the main menu. From there, you can choose the Pokémon you want to give an item to and select "Held Item" to change what they are holding.
* Using Pocket Items: You can use pocket items in battle or outside of battle by selecting them from your Bag Menu.
* Trading Items: You can trade items with other players through the Wireless Communication Menu. You can only trade items that are available in the trade menu.
Note: There is no "storage box" in Pokémon HeartGold and SoulSilver. Once you have an item, it remains in your bag menu unless you use it, give it to a Pokémon, or trade it away.
