BIFL isn't usually really 'for life' since we buy practical stuff as adults.
But.. when I was born in the '60's someone gave me a simple, elegant little steel cup and plate, with cartoon bears engraved in simple lines for decoration.
The plate is still in the cupboard with the general plate population, and the little cup is perfectly sized for a double shot, so it lives on top of the espresso machine and gets used daily, adding special value each time because it's a joy to use, and old like me.
