At our school, we aim for "trash-free" lunches. However, the children typically struggle with plastic containers found at the local supermarket. These lunchboxes seem like a great alternative.
Plus, they contain NO lead, BPA, phthalates, or PVC. The containers are removable and water-tight. They're also microwave and dishwasher safe (top rack only). Unfortunately, they're also quite expensive so consider it an investment. If nothing else, check out their Photo page for hundreds of healthy lunch ideas!!
