I have a couple of magnetic knife bars on the wall in my smoking porch. I stick some tins, without warning labels, on them. If the tin has a warning label, then it gets recycled.
Some photos may be in order?I decorate my garage / pipe lounge with empty tins. My garage has plywood. I simply put a screw through the empty tin and into the wall. Then I twist the tin lid onto the tin that is anchored to the wall.
I made a fire making kit out of a Bob Ross mints tin, and made a very successful trade with it at Wasteland Weekend this year. I'll be using some Cult tins to do the same again for next year.I actually read an article somewhere about Altoids tins that people turned into sewing kits, survival kits, and even a radio. Don't ask me how they did a radio, but I suppose the sky is the limit if you're imaginative enough. I assume tobacco tins could be used similarly.
Use a blow dryer. The heat will loosen the glue enough to peel it clean.I am keeping tins that have pictures I like (Nightcap, Black House etc). Haven't figured out a way to remove the labels safely so I could stick them in my journal. Other than decoration when I buy bulk I dump them into the tins or when I carry out.
