I haven't done any transactions yet but if the original box isn't available I would try and stick some moulded styrofoam around the muzzle, and then have some packing nuts or something..
To prevent it from looking like a gun, putting it in a box is a good start.
Is God willing to prevent evil, but not able? Then he is not omnipotent.
Is he able, but not willing? Then he is malevolent.
Is he both able, and willing? Then whence cometh evil?
Is he neither able nor willing? Then why call him God?
