The 2 big jars have Summertime 2012 (200g in each jar)
I have a jar + tin of Squadron Leader (100g), a jar and a tin of Night Cap (100g), A jar and a tin of Full Virginia Flake (100g)
I agree summertime 2012 isn't sealed, but I get through it fairly quickly. I have stored 400g of Summertime 2012 in the jars and smoking through the 4 tins which will last me a couple of months. In fact now, one of those tins is nearly empty and I only brought it recently!
Lastly, 3 small jars have about 10 zip lock bags of different tobacco in each, one jar has different oriental tobaccos, one jar has different English Tobacco's and one tin has different aromatics. All 5g testers.
