The Space Saver Cup means no more wasted space when packing a cup. This unique design from Olicamp is designed to fit over the end of a round 1 quart (1 liter) Nalgene, as well as most other rounded bottles of the same size, eliminating the wasted space of packing a traditional cup. Made from high quality stainless steel, the wire handles fold flat to save space and extend enough to use the cup to cook without burning your fingers. Also great as a measuring cup with easy to read graduations on the side of the cup. Save space in your pack with this great camping cup. Capacity: 16 oz.
