This is the container that held persimmon leaf sushi. Made of plastic. Size: Approximately 15 x 13.5 x 5.5 cm The lunch box can be reused for bento boxes, etc. Comes with a special postcard that is only included with this product. Due to the thickness, it will be shipped with simple packaging. Since this container held persimmon leaf sushi, I washed it immediately, but please refrain from purchasing if you are concerned. The postcard will be placed in a mini clear file. #Nara #HelloKitty #Sanrio #PersimmonLeafSushi
