Steel Bottle - 350ml

Yes! These bottles are 100% leakproof. The stainless steel cap screws securely down onto a replaceable LFGB certified silicone seal. Nice and simple - and no plastic!

Our single-wall bottles are expertly crafted from premium 304 grade steel. The steel is thicker than cheaper alternatives and are 0.4mm thick. Whether they survive being dropped depends on a few things - how far and what surface they land on, but in most cases they can take a lot of wear and tear. One customer even told us that their bottle survived being driven over by a commercial mower on his local football pitch! 

These bottles are not insulated so they won't keep your drinks hot or cold. These bottles are great at keeping the weight down. You don't always want to lug around twice the weight and there’s easy ways to keep your water cold - you can add a bunch of ice cubes in the wide mouth or keep your bottle in the fridge the day before you take it with you. The other reason we make single wall bottles is that they use half the resources of insulated versions! We don't recommend freezing bottles - it invalidates the warranty and it can warp the steel. 

No — as a single-wall bottle it's not designed for hot drinks, as the outside of the bottle will get hot to the touch. For hot drinks or drinks you want to keep cold for hours, take a look at our insulated water bottle range.

Yes, our non-insulated steel finish bottles can go in the dishwasher. Please wash the steel cap by hand to look after the seal and thread. The Kids bottle has a powder coat finish, so wash that one by hand too.

Washing by hand:

• Hand wash with mild dish soap and a soft brush or sponge
• Avoid bleach-based or high-alkaline detergents
• Rinse and dry promptly rather than letting water sit inside
• Avoid leaving electrolyte or sports drinks in the bottle for extended periods

Check out our plastic-free cleaning accessories for a bottle brush to go with your purchase. If you need to give your bottle a deep clean - check out our blog on how to clean your water bottle.

Wash the cap by hand in warm soapy water, then leave upside down to dry. Don’t soak or submerge the cap, and keep the cap out of the dishwasher. The carry loop joins the cap through a small opening, and soaking lets water inside. If water gets in, shake the cap out and leave to dry upside down.

Yes — there's no plastic touching your drink. No lining, no coating, no plastic components in contact with the liquid. Just food-grade stainless steel and an LFGB certified silicone seal.

You can use the single-wall bottles for fizzy water as long as you pair it with the sports cap. The metal cap is not compatible with carbonated drinks.

Food-grade 18/8 stainless steel (the material used in all Elephant Box bottles) is non-reactive and does not leach metal into food or drink under normal conditions. A metallic taste is almost always caused by one of the following:

• New product residue. A thin layer of manufacturing oil or packaging material can remain on a brand-new item. A thorough hand-wash with warm water and washing-up liquid before first use removes this.
• Mineral-rich water. Hard tap water or certain mineral waters carry dissolved minerals that can register as a metallic taste, particularly in an uncoated steel container.
• Residue build-up. Tea, coffee, and fruit juices can leave deposits inside bottles over time. Regular cleaning with a bottle brush and, occasionally, a bicarbonate of soda rinse eliminates this.
• Carbonated drinks. The carbonic acid in fizzy drinks can react with trace surface deposits. Rinsing promptly after use prevents this.

If a metallic taste persists after cleaning, please contact us and we will investigate.
