Just received the cups from Emergency Essentials. They are marked Glacier Stainless Sreel Bottle Cup 18 fl. oz. made in china. The handles nestle well and are comfortable to hold. The handles are held on by brackets that are spot welded to the cup, these welds are visable on the inside of the cup.
A 1.5 litre water bottle fits inside the cup, I replaced the GI canteen cup with one of these to save a little space in the BOB.
