A little yellow box

There were always little yellow boxes to be found in Grandad's house; usually in more than one place. Generally one would be located on the side-board in the dining room and if memory serves, possibly in the living room. What am I talking about? I'm recalling Grandad's love of a particular sweet. In my view, these tantalising fruit shapes, with their pictures decorating these yellow boxes, were as I see fruit teas now, as an adult. They smell deliciously appealing, but ever-so disappointing when consumed. Now when offered these fruit gums I'd never refuse; always trying to aim for the blackcurrent ones or raspberry, ~ (they may have been strawberry actually). They always seemed quite brittle to suck at first, then eventually the flavour would come through when you'd sucked them to a stained glass circle. 
I may just go and have to buy some soon to reminisce . . . . .
