At the end of 1999, I received a card and a cup from Cobalt. The cup is able to keep the content hot. May be good for camping. There are some Cobalt guy's autographs on the card. Desa, Stephen, Sean, Pat and more.
It has a cap. The inside is plastic and the outside is lagged by metal.
There are so many autographs of Cobalt staffs. Thank you very much!
