All evolution items are one-time use. Once they are used to evolve a Pokémon, they are considered as used. A player would need to buy more stones should the player choose to evolve more Pokémon. All Mega Stones however, are permanent items but a player must purchase a Mega Ring to use with the respective Mega Stone to Mega Evolve.
