Easy to use, consitantly flat results for optimal organization. Creates Perfectly flat bags. Our trays have been molded to fit the bags to get you consistent results every time. Slimmer bags store more efficiently and take up less space. Flatter bags can stack up rather than slide all over. Easy to Use Our patent-pending design is made specifically for a no fuss, one handed use. As parents ourselves we were frustrated with the alternative options that were difficult to use and often produced bags that were difficult to store, creating wedges that cannot stack evenly. Use in any orentation After placing the bag into our trays you can place it in any orientation in the freezer. Standing upright, on its side, laying on a bag of vegetables, in any orientation you'll get perfectly flat bags. Helps with Orgainzation When not in use, the trays can latch to the front or side of the refrigerator. This keeps them off the counters tidy and helps with organization.
