Vintage TUPPERWARE Quick Shake Mixer Blender Gravy Shaker Maker Eggs Shakes

The perfect gift for a Tupperware groupie.
 
 
It has 844-7 written on its base.
 
The base measures 5.7cm. The top has a diameter of 9.5cm (3.7").
 
It has a height of 19cm approximately when the lid is on.
 
The spout has a flip-top attachment. It doesn't actually attach to the lid, thus why I think it is an adhoc replacement.
 
It is perfect for making gravy, mixing health shakes, baby formula, protein drinks, scrambled eggs, etc. Quick Shake Container. Mix, shake, store, and pour from the one container.
 
It is in good vintage condition. 
 
It doesnt have any cracks or chips.
 
This is vintage Tupperware, not new Tupperware. It is not in as new condition
 
It has markings and scratches befitting a genuine vintage Tupperware item.
 
I am not an agent for Tupperware and this is not new Tupperware.
