DOCMON Stainless Steel Snack Containers

The DOCMON set uses 304-grade stainless steel with a compact, multi-section design suitable for small portions.

The container is described as lightweight and durable, replacing plastic or glass options for everyday use. Best for caregivers who want a small snack box for portion control and easy packing for daycare, short trips, and travel.
