Please recommend a good travel coffee mug

[Marghe87]

I am trying to reduce the amount of money I spend on take away coffees (A LOT!) and would like to purchase a nice travel coffee mug that:
is leak proof/will likely carry it in my bag on the way to the station whilst full of coffee
keeps temperature warm
not too big (I don't need 500ml of coffee)
cute to look at
made with good material (ie non toxic etc)
Do you have any brands to recommend? Price-wise I don't mind as ideally I will be using it for a long time. I guess I'd like to stay within £20 max.
Thanks!

I was given ‘The Touch Travel Mug by Nespresso two years ago and I still love it. I looked up the size etc for you now. They still do them:

Capacity: 340ml
Dimensions: Height 16cm
Base Diameter: 6.5cm, Top Diameter: 8.5cm
Dishwasher safe
£20.00

It’s not too big which is great and I’ve never had a problem with it so far.
