Insulated Bottle 500ml - Steel Cap

Absolutely! All our bottles are made from 304 grade stainless steel which doesn't contain BPA. Our plastic caps and silicone seals are certified BPA free too.

The double vacuum insulated design keeps your beverages cold for up to 18 hours.

No, we do not recommend freezing any of our water bottles! It will invalidate the warranty and warp the steel. If you want extra icy water, pop some ice cubes in the bottle before you head out, or fill it with icy water from the fridge.

While the bottle is designed to keep drinks cold, it can also hold hot beverages. It will keep your drinks hot for up to 10 hours.

Here's the best way to hand wash your insulated bottle:

1. Rinse the bottle with warm water after each use
2. Wash with warm water and a mild dish soap, using a bottle brush to reach the base and a smaller brush for the lid/straw if applicable
3. Rinse thoroughly and leave to air dry with the lid off, upside down if possible, so no moisture is trapped inside

For a deeper clean or to remove odours/stains:

• Fill the bottle with warm water and a tablespoon of baking soda, let it sit for an hour, then rinse well
• For stubborn buildup, a mix of warm water and white vinegar (left for 15–20 minutes) works well before rinsing

A few things to avoid:

• Bleach or chlorine-based cleaners
• Leaving the bottle wet or sealed with the lid on for long periods

Leaving electrolyte drinks, sports drinks, or salted water sitting in the bottle for extended periods.

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.
