Box question


#1

I picked up some shotgun boxes with ammo in them. Two of the boxes had one of the sides come loose. Outside of that they are in good shape. From a collectors perspective is it better to leave it alone. Or try and find an adhesive that can put it back together. There isn’t any rip it just looks like the glue gave up and the weight of the shells pushed it loose.

And the other does having the ammunition in the box preferred or it doesn’t add much. I am still pretty new to all of this
Thanks
