3 SIZES, 4 WAYS TO MIX – Get 6 stainless steel shaker balls in three weights: 2 × 12g, 2 × 10g, and 2 × 8g. Use the 8g, 10g, or 12g ball individually, or insert the 8g ball into the 12g ball to create a 20g combined mixer.

20G COMBINED BALL FOR STRONGER MIXING – Combine the 12g and 8g balls into one heavier nested mixer. The 20g setup delivers stronger mixing action to help blend powders faster and reduce clumps in thicker shakes.

FITS MOST SHAKER BOTTLES & CUPS – Three versatile sizes fit most standard shaker bottles, mixing cups, travel cups, mason jars, and other everyday containers. Choose the weight and setup that works best for your drink.

304 STAINLESS STEEL & EASY TO CLEAN – Made from reusable 304 stainless steel for everyday mixing. Dishwasher safe and easy to clean. Great for protein shakes, creatine, meal replacements, drink mixes, milk powder, and dressings.

Not only can it replace your shaker ball, but it also transforms your cup into a blender. Simply put the ball inside your cup and shake it evenly.
