## Customer Reviews

### ⭐⭐⭐⭐⭐ Doesn't leak and keeps things cool.
*by  on Reviewed in Ireland May 21, 2026*

This little flask is brilliant, I'm delighted with it. It holds enough milk for several cups of tea and cereal in work and it keeps it cold. Also the design is very good because you can flip the spout to pour and don't have to fully open the top but is completely leak proof. I would definitely recommend!
