So I take my Token Of Holy Favor out of my museum to test something and I get hit ONCE by an Ogre, lowering it's durability to 254/255. No big deal I thought, I would just repair it and pof it back to 255 before returning it to the Museum... BUT it turns out it has a hidden Brittle property I wasn't aware of: so it cannot be Pofed back to 255 and now my museum has a piece which doesn't look brand new anymore 
I just don't understand why there are a few items with a hidden Brittle property. It is just plain annoying and doesn't serve any purpose. For sure there is also The Redeemer like this (and of course all champ replicas), and I heard reports of other items such as the Warded Demonbone Bracers and/or the Petrified Matriarch's Tongue, and probably several more. One could wander why they put 2 different flags (Brittle showing, Brittle not showing) in the game.
On that specific arty (Token Of Holy Favor) it is even pointless to have it unpofable in the first place, it's not like it is a hugely overpowered item
