Evernew Ti Companion Cup
Price Paid: $18.50
I bought this off of the internet to go in my older Evernew 5 piece set and it nests in my set perfectly. I wish it was just a hair larger then it would also fit my alcohol stove set also but O-well.
It is very light weight and you are able to cook in it also. The folding handles make it easy to pack most any place. I have been looking for a around 12 oz cup that will fit inside my current cook set, 13.5 oz 400 ml is close enough.
