## Questions & Answers

**Q: 50 year guarantee is that correct ? do we have to send off any guarantee ?**
A: I sent mine back. After 18 months it developed a fault. 2 weeks later new one came. I was not asked to fill out an interrogation questionaire or quibbled at. Brilliant service. By the way, these flasks really do keep contents hot for 24 hours. Tested.

**Q: Hi I see this flask is available in 1.2L size and also in 'large' size.  Can someone tell what is the capacity and dimensions of the large flask**
A: I think what it is...is on the link you are using  thje green 1.2litres is a nomal flask the large one is one with extra protection...I have one of those and it holds the same but is tougher...They really do stay hot (or cold) prob longer than it states on the site... really pleased with mine

**Q: Is the cup stainless steel or plastic on the inside?. Thanks.**
A: It's stainless steel and the water stays hot for hours.

**Q: Why is the RRP so drastically different for the different colours?**
A: I have wondered the same thing myself, however, I do know that some colours are more difficult to produce and cost more, plus good adherence to the base metal can also involve further cost. You'd think they would work out the average and charge that for all colours but perhaps that would be unfair to those choosing the less expensive finishes.
