Chilly’s Big Water Open Letter.

For World Refill Day, reusable bottle manufacturer Chilly’s teamed up with environmental organisation City to Sea to call out “big water” brands for using single-use plastic.

As well as a series of billboards occupying three sites in east London for 24 hours, vans visited the Evian, Highland Spring and Fiji Water offices with each vehicle depicting the reusable water bottle printed with each respective company’s logo, alongside an open letter asking for change.
