Raising three kids, I understand what a mess snack and meal time can be! That's why our silicone bento boxes are designed to handle on-the-go eaters and make cleanup a breeze. The large section perfectly holds a sandwich cut in half. The easy-open lid allows kids to be able to open it during lunch at school but is also secure enough to keep the food in place. 00% Food Grade Silicone Oven safe up to 400º F Cleaning: Microwave & Dishwasher (top rack) Safe Size: 5.5" x 4.85" x 2.5" Dimensions: Large section: 4.57" x 3.33" (Holds a sandwich cut in half) Smaller sections: 3.25" x 2.22"
