Lunch box

Things to consider when buying a lunch box


You know the drill. You open your bag to stash your lunch in the fridge and it’s leaked everywhere. That, or you arrive at school to pick up a teary child with a very soggy school bag. Time to get a leakproof lunch box. According to Mumsnet users, they do exist – just look out for a box that locks or with sturdy closures.


Do you like to bento? If you have a strict meal prep routine, you'll need a lunch box with compartments to help you get the most out of it. You could also get one to help make the kids’ lunches more structured and balanced.


If your children like to carry their own lunch box, look out for one with a handle. And if you want a discreet way of carrying your lunch into work, why not try a chic lunch tote? They fit a surprising amount in, and you can separate your food into different containers.


Be sure to get lunch boxes that can stand the test of time. While there are cheap disposable options out there, it’s much more cost-effective (and environmentally friendly) to invest in a few that clean up well and can stand being crammed into tight cupboards.

Kitchen storage

Are you a Tupperware hoarder? We know the struggle. You need lunch boxes to come in all shapes and sizes, but storing them can get messy. If that sounds like you, keep an eye out for stackable options – they could free up space in your kitchen.

1. Umami Original Bento Boxes

Chic and strong, these bento boxes from Umami will keep your food fresh and protected – meaning you can enjoy a delicious meal every day of the week. Made from BPA-free plastic, this set is split into two large containers (both 600ml) with each one divided into two compartments; perfect for separating your rice, veggies and meat.

The best thing about bento boxes is that they help you stick to your monthly food budget and could save you hundreds a year (as much as £2000), especially if you’ve got a bit too familiar with that café around the corner. Mumsnet users say they’ve helped them break bad habits and that, with these, there’s no reason why you can’t eat well and save money at the same time. Umami also offer a 100% money back guarantee if you’re not fully satisfied.

What Mumsnet users say

“I'm a big fan of a vegan lunchbox…I think that's how I discovered bento boxes. Putting things into little boxes inside the main box is the way to go.”

“I second the idea of a bento box – they come in loads of sizes and shapes.”
