itsu refill flask sparkling water

Itsu is a British-based chain of East Asian-inspired fast food shops and restaurants, and a grocery brand. It was founded by Julian Metcalfe, co-founder of sandwich chain Pret a Manger and founder of Metcalfe's Skinny popcorn.

The itsu refill flask is part of the brand's commitment to sustainability, encouraging customers to reuse containers rather than opting for single-use plastics. While the water within the flask is sourced and bottled in the UK, the brand itself represents a fusion of British business entrepreneurship with East Asian culinary inspiration.

Ownership of the brand remains primarily under its original founder and private investment groups. Bridgepoint, a major private equity firm, acquired a minority stake in 2021 to fuel its global expansion and digital transformation. The company remains headquartered in London, United Kingdom.
