Purchased online. Popular Yumbox from overseas. It's leakproof, and the height of the dividers and the packing prevent the food from mixing even if it's turned sideways or upside down! I already have two and use them, so I'm selling this one. There might be some minor scratches from storage, but it has never been used. I threw away the box. Retail price is around 6400 yen. leakproof Yumbox Bento Box 730 ml Panino (M size) - Pink ★ Tray divided into 4 compartments ★ Size: Optimal size for ages 3 and up to adults. Dimensions 21.5 (l) x 15 (w) x 4.5 (h) cm, weight approx. 500g
