Last year, the lid on the travel mug I’d been using died and while technically it still worked it was becoming awkward to use. As soon as I’d bought it, I realised my mistake because it didn’t fit under coffee machines and while it was leak proof it was always tricky to open and use on the train.

Enter this Circular and Co cup, it’s leakproof, the size of a paper coffee cup, has a lid that you just pop up and down. I also appreciate the symmetry of some of it being made from old paper cups.
Finally, if you break the lid or the cup you can just replace the lid or the cup and not have to throw the whole thing away and there are instructions on how to take the lid apart and deep clean it.
It’s great.
