What's the asking price?
Were I a collector of tobbaciana [which I'm not] I'd probably pay twice the cost of a rare tin for that one.
Not just rare but quite unique.
Companies often gave out sample packs of all sorts of things from a new brand of breakfast cereal to washing up liquid back in the day. I seem to recall sample packs of ciggies [A 5-pack if memory serves]
It's an excellent marketing strategy [if it's a good product that is] so I'm not sure why samples are a thing of the past.
A glass container may well display the contents but not sure if it would be something I'd want in a pocket, especially not near my sensitive bits.
