Dear Grumpy Old Man,
If you where born before 1960 they Will be in either an Oxo or tobacco tin if after 1960 they will be in a coffee jar or something Tupperware. Either way they will be on a shelf made out of scrap contiboard and on mismatched painted brackets. However they will remain lost as one of the first tins,jars or Tupperware will contain something distracting and needing attention!
Should you find them the law of storage dictates any thing need as a pair or more at least one will ping out on opening and disappear down a crevice only to reapear when you have built a replacement or is this just my world?
