Z-Ring

The Z-Ring is an object that allows trainers to use Z-Moves with their Pokémon. The Z-Ring fits on a Trainer’s arm, and Z-Crystals are set into it. If a Pokémon holds the same variety of Z-Crystal, the two will be able to resonate with one another. Crystals that correspond to each Pokémon type have been found in the Alola region.
