Plastic shaker bottles “work” - but only if you can truly clean them properly.
And that’s the problem.
Most plastic shakers trap residue, stains, and odors deep in micro-scratches. Why? Because over time, your workouts beat them up - and bacteria thrives in those tiny grooves you can’t see.
Even if you wash them every day, smells stick around, bacteria colonies build up, and eventually they become unsafe and gross.
So even though plastic is cheap, 90% of them end up in the trash within months - and you’re forced to buy another one, over and over.
That’s why we use 100% stainless steel.
Because with steel, bacteria has nowhere to hide. It’s completely non-porous, easy to rinse clean, and doesn’t hold onto smells or residue.
You get a shaker that’s actually clean, safe, and built to last - without waste or frustration.
