I use Altoids boxes for all kinds of projects plus as storage for fasteners. Most of these boxes have an embossed top that makes gluing a label on difficult. The solution is very simple - put the top on a smooth block of steel. Then place another smooth block of steel over the embossed areas. A few blows with a heavy hammer and the top is almost completely flat. The more the top has been embossed, the more the metal has been stretched. This can cause the flattend top to bulge out or sink in slightly. Certainly flat enough for a label to stick.
A trick I have not tried yet is to heat the center of the bulged surface until it is orange hot. Then cool it with a wet towel. The metal will shrink a bit. I'm sure this will take practice to get right. Anyone done this on think sheet metal?
