We love to pack our Yumboxes with berries, yoghurt, cous-cous, cheese, vegetables, fruit slices, ricecakes, dips, crackers, sandwiches, dried fruit, olives, pasta, mini quiches, even leftover pizza! Your imagination really is the limit with a Yumbox bento box. Yumbox lunchboxes are waterproof for thicker liquids such as dips and yoghurts. They're a great way of providing variety and healthy lunch and snack options for your children at daycare, pre-school, and school or for yourself at work.
