イッシュのいし - Evolution Item
イッシュ地方で初めて発見された、ある特定のポケモンを進化させる特別ないし。白と黒の組み合わせが特徴的。
Special evolution items like the イッシュのいし first arrived back with the second generation of Pokémon, and are now required when evolving Pokémon such as ヤナッキー and バオッキー and ヒヤッキー and ムシャーナ and チラチーノ and シビルドン and シャンデラ. When evolving these Pokémon, this item is required in addition to the candy, and is consumed when used.
How to evolve ヤナップ into ヤナッキー

How to get the イッシュのいし
The イッシュのいし is obtained from spinning Pokestops and Gyms. There is a very low drop chance of around 1% per spin to receive a イッシュのいし or any of the other evolution item, and there is an equal chance of obtaining each of the 5 currently available items.
There's no way to ensure that the イッシュのいし will drop, but with only 4 other items, there's a greater than 50% chance that you'll receive one once you've spun over 250 Pokéstops.
The 7th day streak bonus gives you a very high chance of obtaining one of the evolution item, but it's not believed to be guaranteed.
