The cartons earned the Mumsnet Rated badge after a trial with 91 parents, while keeping the brand in a [sugar-free, low-calorie format](https://www.trendhunter.com/trends/unsweetened-soft-drinks). Orange & Passion Fruit and Apple & Raspberry come in [straw-free cartons](https://www.trendhunter.com/trends/tetra-pak-and-sterilgarda-alimenti), so the packs are simpler to drop into bags and use on the go. Made with Radnor Hills' spring water and natural fruit flavorings, the drink is sold through retailers including ASDA and Tesco, with three-carton packs starting at £1. A three-carton pack from £1 turns a parent-tested school drink into an easy grocery add-on rather than a higher-ticket lunchbox extra. Placement at major supermarkets including ASDA and Tesco widens Radnor Splash's reach with families looking for [sugar-free hydration](https://www.trendhunter.com/trends/capri-sun-hydrate).
