These exquisite chocolate boxes from the 1950s are getting hard to find in any condition as they are so fragile.
Very breakable hard plastic, brittle and often finely decorated. 
This box is from ALLENS SWEETS Melbourne. 
AMAZING DESIGN not dissimilar to a flying saucer having landed, but is, in reality like a fancy sugar bowl with retractable lid.  
Very ornate little feet & edges.
How did this ever survive ??  'Uranium glass green' fluoro lid and cream body.
Base is embossed with Allens Ltd Melbourne in the centre.
This item may clean up better - been in a dusty box for some years.  
Whole item is in excellent condition.   I doubt there is another around, but if so, it would be no better that this lovely example.
It is about 5" x 5" x 4" high.
SEE OTHERS I AM LISTING FROM A SMALL COLLECTION.  GOOD LUCK.  SOME RARE ONES HERE.
PACKED IN A BOX TO ARRIVE INTACT OF COURSE.
