Ever forgotten your wallet or been caught without cab fare? We have, and it's not been a favorite experience. Give the people you care about (including yourself!) a little peace of mind--Cash InCase. Simply roll a $20 (or $50) bill into its hollow cylinder, cap it and forget it. You'll never be caught embarrassingly short again. Use the ring for keys, or slide it through the zipper pull of your fanny pack or purse. You'll always be prepared. (2-1/4" long, 1 oz).
