Octoto bento box stainless steel container was made by advanced manufacturing process. It is rarely achieved in China with such a small volume sheet stamping into a deep three-compartment kids' tableware, since the deep containers are difficult to stretch in stainless steel manufacturing. On the other hand, with the consideration of health and safety, food-grade 304 stainless steel and special high temperature resistant food grade PP were selected for the product. Hence, it enables the plastic components bear up to 120 ° high temperature without deformation. This is another unique point of the product.
