6 Pcs Shaker Balls Replacement 2.1 Inch Stainless Steel Mixing Ball for Protein Shaker, Drinking Bottle

These work great! We have a household of people who make pre workout drinks, so it's great to have extra shaker balls.

I use them to make vinaigrettes and the work well.

These work great for mixing protein shakes! So glad I got them. I didn't want to have to buy a whole shaker bottle because I wanted to use mason jars. These work wonderful with the glass jars I already had. Cleaning them is easy too. All around win!

Like the different sizes for these shaker balls. They are good quality also

Great for any type or size cup/container

I bought these to have a more durable cat toy for our pets to bat around the place. They absolutely love them! Where they'd discard cheap plastic springs after a short play session, they keep coming back to these for more play. The only problem is the "sproing!" as they bounce around the floor at two in the morning!

They came super fast and easy to take care of! I am so happy I have enough. And they don’t get tangled like the others

I’m enjoying both sizes of the stainless steel shakers balls. I use the large one in a quart jar and smaller one in a pint jar. I blend a green drink that is very prone to settling and the shaker balls reblend the drink perfectly. It works to mix protein and collagen powders, as well.
