It is a item to let a Pokemon hold and the Pokemon will not evolve. For more information contact me at likefruit89@yahoo.com. You can find one at Snowpoint City by trading with a girl that has a hauter it is holding one or you can find one in the under ground tunnels

Pokemon Platinum because you can catch more legendaries!
If you don't want a pokemon to hold an item anymore go into the Pokemon menu and then highlight your pokemon. Press the A button to bring up several options. One of them will be Item, select it with the A button and two more options will appear Give and Take. Choose Take and you will remove the item from the pokemon.
