2 Pcs Stainless Steel Ball Shaker Ball Wire Whisk Ball Protein Mixing Ball for Shaker Cup Bottle Mixer (Diameter 1.2inch)

You want balls? You wanna mix em up with your balls? Get theses balls so you got eeeeeem.

These shaker balls are very small and I already lost one of them, but they did work when I used them

These shaker balls work very well. I should have taken note of their size, they were much smaller than I realized.

I bought the 1.5” whisk balls for use in a 12 oz glass bottle and they work well. They are small but I knew that going in. I use both in the bottle without issues. If you’re wanting the traditional size that comes with protein shaker bottles, don’t buy the 1.5”. Otherwise, you should be happy with the purchase

These did not work very well for me. They are not big enough to break up more than a little bit of protein powder at a time, and they’re very flimsy.

I use both in a 20 oz bottle to mix my clear protein and they work great

Much smaller than regular sized shaker ball, not sure who would want these to be honest, not happy

I don't know the science behind this but it worked great to keep my fake Ozempic from coagulating!
