What a classic japanese design! The design of this water bottle is inspired by the iconic Yakult bottles. Many of us grew up drinking one of these a day, very nostalgic! The water bottle holds up to 500ml, and is made fully of recyclable plastic. It's certainly not a single-use item and would be used for a very long time. Unlike many other plastic water bottles, this bottle has a neutral flavour, the water stays fresh & its seal leakproof!
