Thank you for purchasing a Mizu container: it’s a great choice for your health and the environment. Mizu backs all of our stainless steel containers with a Lifetime Warranty against manufacturer’s defects. Scratches and dents from dropping or normal use that do not affect the use or safety of the bottle do not qualify for this warranty. Please note that the paint and graphics on your stainless steel container can be chipped and scratched from normal abrasion, impacts, or repeated runs through the dishwasher, and this is not a defect. Putting your Mizu in the dishwasher will void the Lifetime Warranty. Our one-year warranty for the paint and graphics covers only peeling and flaking due to manufacturer’s defects. The Mizu glass products do not come with a Lifetime Warranty and instead have a one-year warranty against manufacturer’s defects. Mizu uses borosilicate glass, which is more durable than regular glass, and all our glass products are dishwasher and microwave safe. But remember, it is still glass and will break if dropped or mishandled. Breakage from dropping or mishandling Mizu’s glass products will not be covered under warranty. We are proud of our product quality and stand behind what we make, but we will not replace products that show signs of excessive abuse or misuse. See “WARNINGS” below for more information on uses that will void the warranty.



For best results, FILL with preferred beverage, go have FUN, DRINK & REPEAT until fully stoked (or tired.) Please note whether your container is qualified for hot and cold liquids, or just cold liquids. In general, all single walled stainless steel products ARE NOT TO BE USED WITH HOT LIQUIDS. Using these products with hot liquids can cause burns. Mizu’s double wall and/or vacuum sealed products are OK for use with hot liquids. Mizu glass is also OK for use with hot liquids, but only with the provided silicone sleeve. Note that the silicone sleeve only provides minimal temperature protection and the Mizu glass, even with the sleeve on, should not be touched for several minutes if boiling water has been poured inside. Please let the glass and silicone cool and carefully test it before picking up and drinking.



Mizu recommends washing all containers with warm soapy water and a bottle brush for best results. Please be aware some very hot and high water pressure dishwashers can eventually break down and remove the paint/graphics from bottles, so if you want to extend the life of the paint/graphic, please wash by hand.

If you are a California resident, you waive your rights with respect to California Civil Code Section 1542, which provides “A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor,” as well as under any statute or common law principle of similar effect which restricts the release of claims which the releasing party does not know or suspect at the time of the release, which if known would have materially affected the decision to agree to release.
