I used it once, but since the capacity is small, I don't think I'll use it much, so I'm selling it. I plan to ship via Yu-packet Plus. Thank you. This is a plastic container with a triangular design and two compartments, perfect for storing food. - Brand: FOODMAN - Size: Triangular - Material: Plastic - Manufacturer: CB JAPAN CO.,LTD. - Structure: With two compartments Thank you for looking.
