A Pokemon GO Evolution Item is required to make certain Pokémon evolve. Trainers can collect Evolution items by spinning PokéStops. Drop rates for evolve items are fairly low (0.76% – 1%). However, trainers can get 1 guaranteed, albeit random, Evolution Item by completing their “First PokéStop of the Day” 7-day streak.
