Spandit: I'm 99.9% sure that it doesn't have a lining. I wanted to use a tinned food can, but every tin I opened had that white plastic lining. The inside of this tin is the same as the outside. 

Is a tin coating harmful?
I'm actually trying to make a cup out of a smaller tin can, but I can't figure out to attach the handle. The wire is to stiff to go around it, should I poke to holes at the top for the wire? Like this: http://chestofbooks.com/crafts/popu...for-Boys-to-Do/images/Handle-on-a-Tin-Can.png
