Nutrex SportShaker - 블랙 프로스트

The mixing ball does its job perfectly—no clumps in my post-workout shake, even when I just use water and a spoon to stir it first. Lid snaps shut tight enough to toss in my gym bag without a worry, and the black frost coating hasn't scratched after two weeks of daily use.

The frost-black finish looks way better in person than in the photos, and it’s been living on my gym bag for two weeks without a single leak. Mixes my protein powder with just a few shakes, no clumps left at the bottom.

The lid snaps shut with a satisfying click and hasn't leaked once in my gym bag, even after being tossed around. The black frost texture gives it a nice grip when my hands are sweaty, and it cleans out way easier than my old shaker.
