A new type of Lure Module has been added to Pokemon GO, and Golden Lure Modules may be the most valuable one of them all as they turn normal PokeStops into Golden PokeStops.
Unfortunately, obtaining these Gold Lure Modules is far from easy as it requires sending Postcards to Pokemon Scarlet to Violet!
How to Get Golden Lure Modules in Pokemon GO
To get Golden Lure Modules in Pokemon GO, you must send Postcards from Pokemon GO to Pokemon Scarlet and Violet for five days.
This is according to the official Niantic support page, which also says that you can only hold one Golden Lure Module at a time.
Every Gimmighoul Coin you collect means you’re one step closer to evolving Gimmighoul into Gholdengo!

How to Use Gold Lure Modules
To use a Golden Lure Module in Pokemon GO, you must walk up to a PokeStop and tap on it. Then, press the Lure Module Slot and select a Golden Lure Module from your inventory.
Activating Golden Lure Modules works exactly the same as any other Lure Module.

What Do Golden Lure Modules Do in Pokemon GO?
Golden Lure Modules turn normal PokeStops into Golden PokeStops. These Golden PokeStops can give you Gimmighoul Coins and more items than a regular PokeStop when spun.
Additionally, any Golden PokeStop with a Golden Lure Module on it can attract a Roaming Form Gimmighoul for you to catch!
Luckily, there’s another way to catch Gimmighoul in Pokemon GO that doesn’t require a Gold Lure!
