Those biscuits could have another 8mm on their diameter and still fit comfortably in the box.
The runny Mars Bar stuff inside was quite nice, but the outside was dull and tasteless, like those dreadful Oreo biscuits that Cadbury's have been adding to everything since they were taken over by Mondelez International (which makes them both). I want sugar in my biscuits! If I wanted to eat cardboard, I'd eat cardboard.
Thank goodness for Golden Crunch Creams.
