This hard-working spill-proof box helps keep your food tasting like it should. The removable front and back panels let air flow through the box (without messy spills!) for maximum freshening power in your refrigerator, freezer, or any enclosed space where odors tend to linger (like your microwave and closets!). To keep everything fresh, make sure to change your Fridge-n-Freezer™ box every 30 days.
