To ensure the longevity of your Bento Lunch Box, proper care is essential. The compartments and utensils are top-rack dishwasher safe and can also be stored in the freezer. However, the bamboo lid, made from a natural material, requires special attention. It should be wiped with a soft, damp cloth and immediately towel-dried to prevent moisture damage. Material: BPA Free PP & Bamboo Lid Dimensions: 185mm x 105mm x 95mm Capacity: 1200 ml Avoid soaking it or exposing it to prolonged moisture, as this can compromise its integrity. Store the lunch box in a dry area, and occasionally apply a food-safe mineral oil to the bamboo lid to maintain its natural quality. By following these care instructions, you can preserve the functionality and aesthetic appeal of your bento box for years to come.
