I like the way it says it is a Hobbit
Inhibited Bottle! It clearly likes to be left alone and not shown to strangers.
Actually, it sounds like the bottle is inhabited by a boggart! I've not seen ours for a while now. I must make sure the Faerie Door (yes, really) is clear for hi to come in and out...
Now talking of weird collectables, when I was about 17 I remember a guy at school had seen a catalogue in which Tolkien's writing desk was for sale. It had sold for around £300 or so, which is absolutely nothing if you think that this was the very desk which Tolkien used to write all his works on! Wow! And that indeed was my reaction at the time.
