It could be a joke for all I know.
At least reading Seven deadly glasses on tongue in cheek Dezeen design magazine put a smile on my face.
London-based designer Kacper Hamilton created these seven glasses for seven sins which as you might have forgotten are lust, gluttony, greed, sloth, wrath, envy and pride.
The glasses seem quite impractical as far as drinking wine is involved.
It could excite the curiosity of your guests if you buy a set and display them in a choice spot.
Could enliven the conversation.
