Only one with flo-thru technology. The standard of purity. America's no. 1 trusted baking soda brand. Buy 2: 1 for fridge; 1 for freezer. Flo-thru vents expose more baking soda than other similar sized products. Eliminates odors so food tastes fresher longer. While fridge-n-freezer contains pure Arm & Hammer baking soda, we do not recommend it for baking as the granulation is designed specifically for deodorizing. After use, pour down the drain while running warm to freshen. Money back guarantee. Any questions or comments, please call: 1-800-524-1328, 9 am - 5 pm ET. armhammer.com.
