These are the props I alluded to some weeks back. Finally posting them.

I bought about twenty in total. I must confess, it surprises me at quite how few establishments actually sell marbles. Quite glad I got hold of them, they remind me very much of my childhood, when I might add, I had two 5 litre icecream containers full of them. Those were the days, just wondering where the next 'oily' or 'spaghetti' was going to come from.
