Cracked Pot

A peculiar teapot that can make a certain species of Pokémon evolve. It may be cracked, but tea poured from it is delicious.

You can find both Cracked Pots and Chipped Pots as a possible item for sale at the Port Marinada Auction House once you’ve completed the Water Gym Test there. You can expect to pay 15,000+ for each.

Cracked Pots are needed to evolve Sinistea into Polteageist, so long as it’s in its Normal Form. If it’s in its rarer Antique Form, you will need a Chipped Pot instead.
