Optimum Nutrition(ON)“Opti-Lock” protein shaker is a practical item that helps minimize clumps in your drink while staying sturdy and easy to use with one hand. As a genuine, officially distributed product in Japan, it offers peace of mind, and it’s dishwasher-safe—making everyday cleaning much easier to keep up with.
With a 700ml capacity, it’s great not only for protein drinks, but also for those who want to fine-tune the amount of added liquid. The lid area features a “lock” structure, designed to reduce the risk of leaks while shaking. Plus, being dishwasher-safe means you can cut down on hand-washing—handy even after the gym or during your morning routine.
One common downside of shakers is that powder can sometimes remain at the bottom. This model is designed to shake and mix more easily, helping it blend better. Whether it’s before or after sports or golf practice—when you have limited time and you’re on the move—you can get it ready quickly and take it with you easily.
