Laura They don't let me hold the key in my hands
Same for me.
I think it is a positive thing, due if we can touch the key, then we have "some power" over the belt, and it can create conflict.
It is very important that the wearer do not have any possibility of act over the belt.
Do not you think that if we could open the belt, even when keyholder gives us the key, can change the perception about the belt?
For our good, it is better think in the belt as something about we are absolutely overpowered, that gives us the concept of absolute safety that every girl has of her belt.
I think that it is the background of why keyholder does not let us take the key.
