A stainless steel water bottle, compatible with the Aarke Carbonator 3 Sparkling Water Maker. Available in 650ml or 1 litre. ---DETAILS--- Designed in Sweden, the Aarke Steel Water Bottle is compatible with the Aarke Carbonator 3. Made from stainless steel with over 90% recycled content, it's a great alternative to the PET bottle that comes with the carbonator, and will keep water cooler for longer. The bottle has a smooth exterior and double stainless-steel walls with a vacuum to keep your drinks cool and carbonated for 24 hours. A fill line on the inside makes it easy to fill the bottle to the right level, and water should not go past this level when carbonating. The timeless Swedish design blends into any kitchen setting beautifully, and it can be used as an on-the-go water bottle, carbonated or not. Dishwasher safe, hygienic and easy to clean, the bottle is a great way to cut back on single-use plastic. ---BENEFITS--- 'If you prefer cooler water, the stainless steel bottle is ideal. It keeps water cold and carbonated for twenty-four hours, and is a great on-the-go water bottle, carbonated or not.'
