Not being a smoker things like this happen by accident to me.
Got 2 of these Golden Virginia 50g tins
Unlike a normal tin this one is has a lid the same size (as near as) as the bottom
the Dims are, 13.5cm long 7.5 wide 1.8cm deep when closed the tin is or seems to be slimmer than a normal tin (3cm ish).
If it was ally and not steel it would be a good tin, my plan is to spray it or sand it and decant my survival tin in to it to see whats the difference in capacity is, on the tin it saids "for use with your ryo tobacco pouch" might see what one of them looks like?
