From Bulbapedia, the community-driven Pokémon encyclopedia.
The Mystery Box (Japanese: ふしぎなはこ Mystery Box) is a legendary artifact in Pokémon GO used to spawn wild Meltan.
It was first featured in the short video series The Two Professors, where it was discovered by Professor Oak and Professor Willow.
According to Professor Willow, the Mystery Box was made by people who worshipped Melmetal to keep it safe. When the Pokémon splits itself into Meltan, they are stored in the box until it opened again in order for Melmetal to appear. The box will opened when exposed to open air in a natural environment.
After receiving the Mystery Box, the player can access it from their Bag in Pokémon GO and choose to open the box. Once opened, a 30-minute timer will begin, during which wild Meltan will be appearing around the player. The Meltan will stop appearing after the box's timer has expired. The Mystery Box will then remain shut on a three-day countdown timer. Once the countdown reaches zero, the player can unlock the box again by transferring Pokémon from GO to Pokémon: Let's Go, Pikachu!, Let's Go, Eevee!, or Pokémon HOME. Originally, players had to wait seven days to open the Mystery Box; the wait time has been permanently lowered to three to mark the second Shiny Meltan event that took place from April 24 to May 5, 2019,.
The Mystery Box and Incense are mutually exclusive: if one is active, the other cannot be.
Due to the COVID-19 pandemic, the Mystery Box, like with Incenses, has had its effect duration doubled to one hour and spawn rate increased, until further notice.
