Question: how do you use the shiny charm in pokemon let's go?
Answer: Using the Shiny Charm in Pokemon Let's Go After you complete your Pokedex (which isn't as hard as it sounds) you can visit the Game Director in Celadon City. There's a man with a buff Poliwrath standing outside the building you're looking for. Head in and you'll find a floor with the in-game Game Freak team.
