Why choose metal Bottles over single use plastic bottles?

Did you know plastic bottles take over 450 years to decompose? 1 million plastic bottles are purchased every minute across the globe and less than half being recycled. Although the majority of plastic bottles used for water and fizzy drinks are made from PET, a recyclable plastic, the efforts are not being made to reuse and recycle. Metal Water Bottles are a convenient, stylish and environmentally friendly alternative!

What is the difference between Aluminum and stainless steel water bottles?

Aluminum bottles, like the Grom Aluminum Sports Bottle, are more sophisticated as well as lightweight and corrosion-resistant. Stainless steel bottles, like the Geometric Bottle and the Duke Copper Vacuum Insulated Bottle, are sleek and professional looking options.


Aluminum offers a modern, sleeker look for sports bottles. These versions are not squeezable, but they are more durable and professional looking. Aluminum is also light, making bottles easily portable. Our aluminum bottles come with several options for size, shape, and lid.

Stainless Steel

Stainless steel is a solid alternative to lighter aluminum options. These bottles are more polished looking and may last longer. Stainless steel is naturally insulating and will keep water, juice, or sports drinks cool throughout the day. We offer a variety of shapes and size as well as finishes for these sleek bottles.

How to care for your metal water bottle.

Wash with warm soapy water and rinse well before consuming liquids. Are metal water bottles dishwasher safe? Our ranges of personalised metal water bottles are not suitable for the dishwasher. It is recommended to hand wash only.
