I’m seeing these advertised on Etsy and EBay. I have some lovely mugs I want to sell and they appear to be flirt mugs - but I don’t know what makes them such! Does anyone know?
It isn’t linked to the make or designer -Alex Clarke
Doesn’t seem to be the shape - mine flare at the top but I’ve see. Plain up and down ones
Not the pattern I don’t think - so what is it??
