Karma scissors don't work on all untradeable items, only certain ones that are marked with a special attribute. This nose will NEVER get that attribute because it's not supposed to be permanent, so Karma scissors won't work on it.

So Karma scissors don't work on impermanent items? I know that some versions have expiring Maple Items (they make them expire in like 5 years or something). Assuming that their other items worked the same way but were untradeable, does that mean the Karma scissors won't work for those either?
