sold on 10 mil buyout
From the wiki: Enhancive hiders can be used to hide non-scripted and non-armor enhancive items when RUBbed. Scripted items such as enhancive Joola jewelry will not be hidden. They can also be used to detect enhancive items by waving the mystery item at the held pin, and to detect empty enhancive items by TOUCHing the pin when the items are worn and visible.
