COREGROUND Stainless Steel Shaker Balls, 2 Large & 2 Small, Nested Mixing Design

COREGROUND 316 Stainless Steel Shaker Balls are replacement mixing inserts for blending powders and other drinks, with a nested ball-in-ball design and two large plus two small balls.

• 316 stainless steel — marine-grade metal designed to resist rust and corrosion.
• Nested ball-in-ball construction — adds mixing action to help break up powder clumps.
• Use the balls individually or nested — supports different drink and mixing needs.
• Smooth edges and alkali-resistant construction — help minimize cup scratches and allow top-rack dishwashing.
• A multi-piece replacement set — provides backup when shaker balls are lost.

Loose shaker balls can be easy to misplace, while drink powders may leave stubborn clumps after shaking. COREGROUND’s replacement set is made for everyday drink preparation at the gym, at work, or in the kitchen, and its two sizes give you options for using the balls separately or together.

How does the nested design mix drinks?

The smaller ball fits inside the larger one to form a ball-in-ball mixer. This arrangement creates double the mixing power and helps break down stubborn powder clumps for a smoother blend, saving time during preparation. The 316 stainless steel construction is designed for rust and corrosion resistance, including when used with high-acid fruit smoothies and electrolyte drinks; it also helps keep beverages clean and odor-free.

• Use the nested pair when mixing powder-based drinks.
• Suitable for protein mixes, office matcha, and homemade kitchen dressings.

Will these shaker balls fit my bottle or tumbler?

COREGROUND shaker balls are sized to fit most standard shaker bottles, travel tumblers, and water bottles. The set includes two large and two small balls, so you can choose a size for your container and mixing routine. Use one ball on its own or nest the two sizes together; the set is intended for standard containers rather than a guaranteed fit in every bottle design.

• Four balls total: two large and two small.
• For use in most standard shaker bottles, travel tumblers, and water bottles.

How do I clean the balls, and what comes with the set?

The balls are suitable for top-rack dishwashing, making cleanup straightforward after a drink or workout. Their alkali-resistant construction supports this cleaning method, while smooth-glide edges help minimize scratches inside cups during use. Along with the four mixing balls, the set comes with a storage case, a mesh bag, and a manual.

• Place the balls on the top rack for dishwasher cleaning.
• Store or carry them with the included case and mesh bag.

This set suits people replacing lost shaker balls or keeping spare mixers on hand for protein drinks, matcha, smoothies, and dressings. It also makes a practical gift for fitness enthusiasts. With two sizes, a nested mixing option, and included storage accessories, COREGROUND provides a replacement set for standard drink containers and everyday mixing tasks.
