## Questions & Answers

**Q: Does anyone know if you can get replacement  seals for this?**
A: I've just looked at mine and the seal is  an elastic band.  If you could find some of that depth and thickness, it should be ok.  If not - elastic bands are always useful.

**Q: Is this suitable for fizzy drinks? i.e. when there is a fizzy drink in does it fizz up sometimes when you**
A: I wouldn't personally use it for fizzy drinks as the gas makes it expload from the sip hole xx

**Q: How much liquid does it hold？**
A: Good mug and a half

**Q: Will it fit in a standard car cup holder?**
A: No it doesn't well not my car. Bottom too round. But I do like the cup nice size and feels comfortable. Much admired too.

### ⭐⭐⭐⭐⭐ Really good travel mug
*by K***R on 17 January 2026*

I was sceptical about this product however it is a really good product. Keeps hot drinks warm for ages and is leak proof. Nice size also.

### ⭐⭐⭐⭐ Great mugs. 2 purchased, one leaks, the other doesn’t!
*by K***L on 13 October 2025*

These travel mugs are great for keeping drinks hot for a long time. They look nice and have great colours. Nice and easy to clean too! I have purchased 2 of these, one black, one teal. The black one is perfect with no leaking. But annoyingly the teal one does leak from the lid so any slight tilt, and it spills out the top! Not sure if I was lucky to get a non leaking one… or unlucky to get a leaking one! 😅 Other than that, these are great travel mugs!
