These 30-compartment serving trays with lids are designed to help organize small portions for snacks, meals, or meal prep. The set features 6 divided sections per tray, each measuring about 10 in. Dia and 1.2 in. tall, and the stackable design helps save cabinet space. The trays are made from food-grade PET plastic, are BPA-free, and are built to resist breaking or deformation with minimal odor. They are safe for refrigerator use and everyday handling, though they are intended for dry foods rather than liquids. The lids fit securely with a fluted edge to help prevent slipping and keep contents covered during transport. They are suitable for a range of settings, including home use for picnics, camping, or potlucks, as well as commercial environments like restaurants, bakeries, dessert shops, and hotels. Beyond food storage, the trays can hold a variety of small items such as craft components or sewing notions, making them a versatile option for organizing and transporting everyday supplies. Because the components are designed to stack neatly, storage remains orderly, and the clear design lets contents be identified at a glance. The set is lightweight for easy transport and the modules align for precise stacking. Compact when empty. Color: Black.
