I have this Coleman insulated stainless steel mug that I've had since I can't remember when, at least 20 years, probably much longer. It's sufficiently good that I sometimes use it for drinking coffee at home when I want something that'll keep hot for a bit longer than a standard ceramic mug. Best thing about it is that it has a nice thin lip so you don't get that "drinking out of a tin mug" feeling when you're using it. Also indestructible, it's been dropped down almost as many hillsides as me.

BTW, the fluffy red blanket is covering the black beast (aka Lab ESD testing technician) who is sleeping for the first time in about two weeks somewhere other than the Digikey box that's too small for her that an FPGA board came in.
