Stainless Steel Round 1 Tier Bento Box | Made in Tsubame Sanjo Japan

These round stainless steel bento boxes are made in Tsubame Sanjo, Niigata Japan, the capital of Japan's high quality metal products. They have been made with integrated IKD stainless steel, which integrates copper with SUS304 stainless steel, providing them with antibacterial properties. Coming in two sizes of 480ml and 290ml, each container is not large in itself, but you can stack two containers and secure with the accompanying elastic strap to create a 2 tiered bento box. The underside of the lids have a replaceable silicone gasket to seal and stop leakage (although not prevent), and they can be removed and washed. These bento boxes will last for years which makes them cost-effective over the long term and extra eco-friendly. While they are not microwave safe, they are a perfect option for those who do not want to use plastic.
