How to Choose a Bento Box in the UK – Buying Guide
In order to find the right bento box for you, it’s essential to consider factors such as durability, capacity, and convenience. In this section, we will explore the pros and cons of the different materials and styles that are available.
Metal or Plastic – Which Material Is Best for Your Needs?
Since you are likely to use your bento box every day, it’s important to choose a material which is suitable for long-term use. As well as being durable and lightweight, you may require a container which is microwave or dishwasher safe.
Stainless Steel Is Sturdy and Easy to Clean, but Not Suitable for Microwaves

Heavy-duty and reliable, a metal bento box will keep your food secure until lunchtime. The smooth surface of metals such as stainless steel means they are easy to clean by hand and do not absorb odours, making lunch prep quick and effortless! Another plus is that metal is free from phthalates and BPA.
However, steel does have some disadvantages. As it is not microwave-safe, this kind of bento box is only suitable for food that you want to eat cold or hot food you'll be eating soon after preparing it. Acidic foods such as tomatoes and rhubarb may also cause the bento box to corrode over time.
Plastic Is Lightweight and Microwave-Safe, Perfect for Heating up Leftovers

Due to concerns over health issues, most plastic bento boxes available online are certified BPA- and phthalate-free and so are safe to use. They are an affordable choice, and the variety of designs available means that you’ll be sure to find one that not only falls within your budget, but that matches your personal style too!
Choosing the Style of Your Bento Box
Multiple Tiers Can Be Used to Keep Foods Separate

This means you can keep savoury and sweet foods separate, or you could even take all three meals of the day with you to work! A popular way to use the tiers is to put rice or noodles in one, meat and/or vegetables in another, and dessert in the last tier.
If you don’t need to use all of the tiers, you can typically remove one or more and still use the bento box as desired. Being able to adapt the container to suit your needs is convenient if you are trying to watch your portion sizes, or if you simply want to have smaller meals.
Removable Compartments Allow You to Change up Your Lunch Each Day

These interchangeable compartments are also useful for controlling portion sizes and ensuring that you get your five-a-day. You can easily include a range of different fruit and vegetables in the different sections.
Best of all, you can keep salad dressing separate from your greens – no more soggy lettuce at lunchtime!
Choosing the Right Size for Your Needs

However, if you are looking to lose weight, you may want to buy a bento box which is smaller in size. For example, reducing the capacity by 100 ml should help you to control your portion size.
When buying a bento box for a child, the capacity is much lower – 400 ml is ideal for children aged 3-5, and 500-600 ml is recommended for those aged 6-11.
Insulated Containers Keep Your Food Hot or Cold, Whatever the Weather

Although this kind of bento box can be a little bulky and is typically more expensive than other types, it is extremely convenient and eco-friendly because it doesn’t require gas or electricity.
In order to make sure that the container stays hot or cold as required, you will need to fill it with either ice cold or boiling hot water for approximately ten minutes, and then drain it before putting your food inside. The vacuum technology will keep your food at the desired temperature so it is ready to eat at any time.
Go For Leakproof Containers to Avoid Mess and Keep Food Fresh

As well as being mess-free and allowing you to bring soups and sauce-based meals on the go, the tight seal on leakproof bento boxes will keep your food fresher for longer.
This means there’s no risk of your sandwiches becoming mushy or yoghurt seeping into savoury snacks. Just in case, though, try to keep your bento box upright if you’re commuting or travelling.
Check for Extra Features Like Built-in Utensils and Sauce Containers

The addition of a small leakproof pot means you can easily jazz up your meal with some sauce or a dressing.
