I used this a few times after purchasing it and then stored it. I'm selling it to someone who needs it. The following is an excerpt from the manufacturer's description: This dressing shaker can do everything from measuring to mixing, pouring, and storing. Just add your favorite seasonings and oil, and shake to make homemade dressing! With its measuring marks, it serves four functions in one: measuring, mixing, pouring, and storing. You can use it not only for dressing but also for making sauces and original drinks.
