Ella Shaker | 20 oz med blenderkugle

The 20 oz size fits perfectly in my car cup holder, and the blender ball breaks up my protein powder with zero clumps. I've been using it daily for a month now and the seal still hasn't leaked once.

The blender ball does exactly what it's supposed to—my protein shakes come out totally smooth with no clumps left at the bottom. The 20 oz size is perfect for my gym bag and the lid seals tight enough that I can toss it in without worrying about leaks.
