Got to ask, why do you want a tin box ? I doubt you will be cooking much in an altoid box.
You could perhaps make more char using the metal box.
For fire kit supplies why not use oval film cans ?
If I was looking for a metal box without a hinge I
would check out my local Spice Store or Cost
Plus for small metal boxes.
OR
Just do as advised and wrap the altoid Box with
rubber repair tape.
