    Perfect flask
  

*by A***N on Reviewed in the United Kingdom on 30 September 2020*

I scrutinised the reviews before purchasing as I wanted a good flask for long distance walks. This came up with great reviews, and rightly so. The drink is extremely hot and is maintained for several hours. Handy spout which means you can keep the lid on when pouring. The only downside I would say is the screw thread is awkward and you have to be careful not to cross thread it, allowing the heat to escape. I got the matt black as it was mainly for hubby to use, and he loves it, it is very striking to look at, even comes with its own little cleaning brush.

Je suis ravie de l’achat de cette bouteille isotherme. Le produit correspond tout à fait à la description. La couleur noire mate est très jolie et surtout le goupillon vendu avec est juste génial. Je l’utilise d’ailleurs pour d’autres bouteilles isothermes qui pour le coup n’ont pas été vendu avec!!J’ai même reçu un très gentils mail personnalisé pour me demander si j’étais satisfaite du produit et la facture avec.Bravo au fondateur de Milu!!
