Evolution Items
Evolution Items can be used to induce evolution on a Pokémon who is compatible with that evolution item. The evolution items disappear when used, even if the Pokémon's evolution was declined when prompted.
When it comes to learning moves, it will only learn the moves that are listed for the evolution. However, an evolved Pokémon is still capable of learning its pre-evolution's moves via Playerdex if it has fulfilled that pre-evolution's level requirement for the move; modifying your Pokémon's attacks will cost 500 PokéMoney multiplied by its level.
GMs or Devs will not revert the evolution if you aren't happy with it.

Held Evolution Items
Due to the lack of ability for Pokémon to hold items in PWO, held items that induced evolution upon trade in the Nintendo games function identically to evolution stones in PWO; you have to select the item from your bag pack and select what Pokémon to use it on when prompted.
These items do not have availability from NPC vendors, but they can be purchased on the Token Store. Additionally, the Dragon Scale and Metal Coats are known to be an occasional drop from Pokémon in the Horsea and Magnemite evolution lines, respectively.
