That's neat..... I like the fact the two tins are supplied with resealable plastic lids (someone was actually useing their head for more than a hat rack!).
The French pâté and corned-beef tins of the 70-80's had a metallic cover that could be closed back but it was always leaking and imagine the pâté or corned-beef jelly/juice melting in your backpack, hmmm yummy…
