the bigger 8 dl one is for eating the smaller is for drinking. They are good kit, but are prone to cracking in severe cold.
They are available in a variety of colors in just about evety store here that sells even vaguely outdoorsy stuff. if you get a big bunch you can get them with your logo on (same as with the folding ones).
Logo! You're teasing us now!
