マーベル プロテインシェイカー

The agitator in the lid does exactly what it promises — my greens powder mixes smooth with zero clumps, even when I'm shaking it one-handed mid-workout. Lid seals tight enough that I've thrown it in my gym bag sideways without a single drop leaking out.

I was pleasantly surprised by how well the built-in agitator works—my protein powder mixes completely smooth without any clumps. The lid seals tight enough to toss in my gym bag without worrying about leaks.

Finally a shaker where the agitator actually gets rid of all the clumps without me having to shake it for two minutes. The lid seals tight enough that I can toss it in my gym bag without any worry.
