Specially designed for carbonated drinks the Mobicool MDB 50 vacuum tumbler is absolutely “bubble-safe”. The 0.5 l leak-proof stainless steel bottle comes with a hygienic stopper that allows safe handling with only one hand. There is no escaping of the carbonic acid and no spurting when you open it. A practical tumbler for use on-the-go, the lightweight single-wall bottle is easy to carry. It conveniently fits into the cup holder in your car and the bottle holder on your bike. Easy to clean and hygienic, it can be reused over and over again, so it's an eco-friendly option too!
