Harrogate Spa Water has launched a 330ml size PET bottle designed to fit into kids’ lunchboxes.

Available in both still and sparkling varieties, the new size is aimed at younger children who find bigger bottles too heavy to carry and is easier for small hands to hold.

The new format, which is available in cases of 24, sports the brand’s signature black and silver livery. The company said packaging was important to youngsters and described them as "a target audience for whom stylish packaging is just as important as the product itself".
