I bought Punch black shoe polish the other day.
Gone is the military-like metal container of nostalgic times, replaced by a limp plastic container with a sweet smelling water-based polish, and it is made in Turkey, very Turkish delight almost in fragrance.
The old tin is 50ml, the new plastic one is 40ml. That's 20% down. Because the new one is plastic you would think that the lightness is due to the material, so they reduced the content. I wouldn't have noticed had I not compared the old tin at home.
The smell of the old shoe polish is distinctive and was a feature of ritually polishing my shoes/boots as a child/adult for school, football, church, work etc.
I will keep the old tin, it will look good on a pub wall no doubt in 50 years time.
