A: All our stainless steel drinking containers are made of a premium food-grade type 304 stainless steel containing 18% chromium and 8% nickel with documented raw materials testing. This material is chosen for its consistent quality and performance characteristics of not leaching chemicals, staining, corroding or rusting. The inside of our bottles arefinished using an electrolytic charge and dolomitic sand blasting.

A: No, our containers are made of premium type 304 18/8 stainless steel which is used for many food and medical applications; it does not require a lacquer layer and will not leach chemicals, stain, corrode or rust.

A: We have a testing chain-of-custody process to ensure we are delivering drinking containers that meet international food-grade standards.

A: This is a lead-free, argon gas welding seam from the construction processes. We use a premium type 304, grade 18/8 stainless steel with raw materials testing. The rolled steel sheet is formed into a tube and welded using lead-free argon gas. The stainless tubes then go through a series of hydraulic expansion and heat-t reating processes to create the specific model shapes. Finishing of the inner container is done with a combination of dolomitic sand blasting and an electrolytic charge. Unlike aluminum drinking containers, stainless steel is inert and does not require a lacquer coating on the inner surface; often these contain BPA.
