How to get it
- Send a Pokémon from GO to Pokémon HOME or to a compatible Pokémon: Let’s Go game.
- After the displayed cooldown, send another Pokémon to reactivate it. The normal cooldown is three days; events can alter it.
How to use it
- Open the charged box from Items when you have time, balls, and storage for Meltan.
- The box remains in your inventory after use and can be recharged again.
Worth knowing
Use Pinap Berries to work toward Melmetal’s 400-Candy evolution requirement.
Shiny Meltan availability is event-dependent. Opening more boxes outside a Shiny-enabled period does not enable Shiny encounters.
Plan a Meltan Candy session
The Mystery Box is particularly useful for attracting encounters while stationary. You can prepare balls, berries, and free Pokémon storage first, then spend the hour catching rather than traveling to find spawns.
Using the ordinary three-Candy catch reward as a baseline, 50 Meltan catches supply 150 Candy. If all 50 are caught under a regular Pinap Berry’s effect, that becomes 300. Transferring 40 unwanted Meltan afterward adds another 40 Candy at the normal transfer rate. These are planning examples, not a promise of a particular spawn count or catch success.
Keep the Meltan you want to evolve before transferring extras. A good session can build Candy and Stardust together, but the box does not remove Melmetal’s separate evolution cost.
