Evolutionary items

Main article: Evolutionary Items

As secondary functions to their evolutionary usages, various evolutionary items will oftentimes produce a passive in-battle effect when held by the Pokémon.

Due to the expendability of all evolutionary items, they will be lost when successfully used to evolve a compatible Pokémon.

Berries

Main article: Berries

Akin to various restorative and curative items, such as potions, berries are also out-of-battle-usable; their niche over more inorganic items in that regard is that they are self-consumable by the holding Pokémon in battle, meaning they will be auto-used when the conditional thresholds are met for them (the onset of a status ailment, per se).
