Jugs
I'm at that age where I now go to dinner parties more than I go to the pub. Whilst around a friends house I watched as the hostess poured the dessert cream into a jug, so that it looked better on the table than the pot it was bought in.
At the end of the meal whilst I was helping clean up, she poured the leftover cream back into the pot, to put it back in the fridge. When I asked why, she said, because the pot has a lid and her jugs do not. I avoided all double entendre by concentrating on how easy it would be to design a range of presentable vessels with lids, so she could put her jugs on the table and in the fridge, without the cream spoiling or her having to use cling film (saran wrap/plastic wrap).
