Does anyone know what the use is for the snap hook in the detachable key bell that comes on a Hina MM? The bag comes with a pouch like a Neverfull but it has a strap with a hook for that and a place inside the bag to connect it. Even if you snapped a key (or anything really) to the extra exterior snap hook it would dangle outside of the key bell and would look strange IMO. And I am not referring to the snap hook on the side that is used to cinch in the sides of the bag into a different shape. 3 SAs at the store didn’t know what it was for either. Anyone know what this is for?
