I recently purchased this item at Madu, but after reading the instructions, I discovered it's not microwave-safe, so I'm selling it without using it. I've opened the package, so I've listed it as "like new," but it hasn't been used. This is a women's size. The purchase price was about 5,000 yen. It's a dark brown wooden bentwood lunch box (makage wappa) with a fabric strap, making it convenient to carry. - Shape: Oval - Material: Wood - Color: Dark Brown - Band: Fabric strap - Size: Approximately 20cm x 10cm x 6cm Thank you for looking.
