PureSeal™ is our custom-formulated, food-grade silicone seal designed to perfectly fit the Steel Shaker’s lid without the need for plastic. Unlike many generic silicone or rubber seals, PureSeal™ is engineered to be entirely microplastic-free, BPA-free (as well as any other Bisphenol variants!) and free from harmful fillers — giving you a clean, safe, and tightly sealed shake every time.

Unlike most shakers, ours contains zero plastic — no caps, lids, or interior coatings. Only premium grade 304 stainless steel and food-grade silicone.

While the Devoted Steel Shaker won’t be damaged in the dishwasher, we recommend handwashing to preserve the finish.

While it’s not double-walled insulated, the solid stainless steel design utilizes premium grade materials, which help to maintain beverage temperature far longer than plastic shakers.

No — we use high-grade rust-resistant stainless steel that’s built to last, even with daily use.

The shaker holds 700ml, designed to fit seamlessly in most car cup holders and gym bags.

While it can technically handle hot liquids, we recommend using it for cold or room-temperature drinks to preserve the seal.

Plastic shakers can leach microplastics, stain, and retain odor. Ours is microplastic-free, odorless, and built to last.

We ship globally — including Australia, the US, Canada, the UK, and more.
