Rarity's Key of Generosity. On a visit to Canterlot, Rarity remembers the value of her generous spirit, and is gifted a spool of rainbow colored thread. This thread transformed into her Key of Generosity, helping to open the chest at the Tree of Harmony, and imprison Lord Tirek once again. This lovingly crafted replica Key of Generosity will always help to keep Rarity's Spirit of Generosity in your thoughts. Drape on a chain as a necklace, or add a metal ring and use as a keychain. Key is approximately 3" long.
