MUJI's viral bento box with built-in sauce cup wins over Japanese families

MUJI's "Lunch Capsule" bento box, featuring a built-in topping cup in its lid, has gone viral after a mother shared her middle school daughter's enthusiastic request for it, with users praising its clever design. The vertical, drink-bottle-shaped container allows sauces and ingredients to be stored separately in the lid's cup, making it ideal for transporting noodles, salads, and other meals. It is microwave-safe when disassembled, and comes in 350ml and 450ml sizes priced at 590 and 690 yen. User reviews highlight its leak-proof performance, versatility for rice and noodles, and convenience for outdoor use, with many calling the design "revolutionary" and predicting sellouts.
