It seems like you might be referring to a rice storage container with a double-layer design. Double-layer grain storage boxes are designed to provide an additional layer of protection for rice and other grains, helping to keep them fresh and free from contaminants. These containers typically have two separate compartments or layers that allow you to store different types of rice or grains separately.
Airtight Seal: To keep the contents fresh and prevent moisture or air from entering the storage compartments.
Transparent Design: Many containers have a transparent or semi-transparent design, allowing you to easily see the contents and monitor the quantity without opening the container.
Separate Compartments: The double-layer design often includes two separate compartments, enabling you to store different varieties of rice or grains in one container.
Easy Access: Lids or openings that make it easy to access the grains without having to open the entire container.
