Color irrelevant (up to personal preferences) and specific model w/e, but that aside… good god these mugs really are fantastic:

* they just look plain good, no unnecessary flourishes and the few "unnecessary" features (the locking lid) turn out to be pretty much necessary in the end

* the opening mechanism is just perfect, it has great feedback, is hard to misuse, it's extremely well designed on its own, the double-action opening is just gorgeous

* the entire assembly trivially comes apart for inspection and cleaning

* the heat retention is so good it's a bit too good, filling with fresh coffee early morning and scalding your tongue all the way to mid-afternoon is a bit extreme

We have several similar Zojirushi products at home (SM-KHE48BA) and I'm convinced that they violate the laws of physics somehow. I've never had a vacuum flask that works so well.

Zojirushi neurofuzzy rice cooker. I love it!

I have one of this and you will have to pry it out of my cold, dead hands.
