I also looked at that. Spent some time trying to decide.
We have a soft sided cooler we use as an ASB when heading out. I normally keep the flares/gun/smoke etc.. attached to the handle of that. This would have to live some place on deck for us. And like the other comment, I am not sure others would understand it.

The beauty of our soft sided cooler is we use it as a cooler when ashore. So, ALL the items get looked at as we prep to go. That way I know the dates & the condition of ALL the stuff in it.

Decided it's a new toy we don't need just now.
