"Love it! I bought the wide mouth insulated flask 350ml in lovely bright orange. Leak proof so far and it is really sturdy. I've tried it with both iced and hot drinks. Keeps them at the temperature I want for ages. Very happy with it". - Katriona J.

Very good. Had multiple products now all very good

Orange Flask

Lovely looking flask. Having used it with a hot drink I have to say it isn't as useful as a Thermos mini flask with the attached cup. The problem with having a hot drink in it for me was that it was almost too hot to drink using the spout. I ended up pouring it into a cup which kind of defeats the object. I will keep it for summer cold drinks use. Lovely build quality and looks the business though.

I got the lunch box and snack box combo and they’re just brilliant xxx

The orange flask/drinking cup is excellent and I love the colour. Unfortunately it doesn’t fit in my vans cup holder or my mates van cup holder.

Best drink bottle ever

I bought one of these bottles and have found it so good that I use it daily. It keeps my water cool throughout the day, is designed so to be easy to drink from and is very strongly made. My son liked it so much that I had to buy a second one for him.
