This is a vintage Slim Shaker electric mixer, model 10.
This milkshake maker turns on when you press down the motor-housing on the clear plastic cup.
The motor-housing and cup do not screw onto each other; they just fit together.
This mixer is 11 1/2" in total height.
The cup is 5 3/4" in height, not including the higher-rim.
The higher-rim is an extra 1/2"; it fits into the motor-housing, and turns the motor on, when you press down the motor-housing.
The cup can safely hold 3 cups of liquid.
This item is used.
The cup has scratches, but, otherwise, there is no damage (cracks, breaks) to this item.
I show this item working in the 3rd and 4th photos.
You can see a video of this item working, if you find this same item on Face book, with the same price, and same text.
This Slim Shaker has been cleaned inside and outside, including inside the motor-housing.
The motor has been oiled with 3-in-1 Motor Oil.
The electric cord is 55" long.
