## Description

From the manufacturer

Review: Good quality lunchbox, for those wanting an alternative to plastic. - I specifically wanted a Stainless Steel lunchbox, as I don’t like plastic, and found glass alternatives too heavy and fragile. The lid on this has an integrated valve, which helps to ‘vacuum seal’ the lunch box, making it leakproof, this does however make it a little tricky to remove, so I perhaps wouldn’t recommend it for younger children. It is very hygienic, easy to clean, and does not get ‘tainted’ by stronger smelling foods, nor impart any taste to food stored within it. The silicone strap and integrated fork are a nice touch, as is the slot-in divider. It is a decent size and not too heavy. I am happy with my purchase.
Review: Excellent build and design but heavy - Seriously well built lunch box/food storage container. Valve on lid allows you to achieve a vacuum seal once the lid is on. There's a single moveable internal devider to seperate food. Also a rubber retaining band with a built in fork storage slot, so the lid's never falling off of this. Stainless steel fork is provided with this set too. Best part about this is it's truly long life. Lid, rubber retaining band and rubber valve seal are all available as spare parts, at a reasonable price point. If used alone the base only (not lid) is oven safe. So you can transport and then cook with this product. Sadly, at this build quality weight is an issue. I carry a backpack daily, so am prepared to accept this as part of my daily carry. This is the best lunchbox/ food storage I've seen for ages, just be willing to accept the weight issue as it's seriously well made!

## Features

- Warning:Not suitable for children under 3 years. For use under adult supervision
- Multi-functional: the 3-in-1 box is truly a diverse food container that allows you to securely transport your lunch, cook dishes in your oven, and even store pre-cooked meals in a freezer
- Leak proof: The stainless-steel box lid is specially designed with an over-mould silicone to prevent any spills or leaks
- Vacuum security: The vacuum valve on the lid provides extra security and leak proof functionality. Lift the valve to open and push down to securely close
- Friendly: 100 percent plastic-free lunch box design. The box, fork and food divider are made from quality stainless steel. The strap and mould are made from BPA free silicone
- Practical accessories: a stainless steel fork is securely help in place by a silicone strap and a removable slider/ diver allows you to organise your food with ease

## Questions & Answers

**Q: I read that this was dishwasher safe but in the instruction manual, it said not to wash the lid in the dishwasher?**
A: The Lid has a silicone seal around its edge which may cause cleaning issues if food particles get trapped under the silicone seal, i believe this to be the only issue, i've placed every part of this in the dishwasher lid and all, i just give the lid an extra wipe down afterwords, about 60+ complete dishwashes later lid and all still perfect. i hope this helps.

**Q: Is this microwave safe?**
A: Some metals are microwave safe, check your microwave instruction manual.

**Q: Does it keep hot food warm?**
A: No, it's a single skin construction.

**Q: what is the country of origin?**
A: UK

### ⭐⭐⭐⭐⭐ Stylish and versatile lunch box
*by B***I on 1 September 2020*

I'm really enjoying this lunch box. I used this almost everyday for lunch at work before lockdown and now I use it at home to store food. It's nice that I can just pop it into the oven to heat as well. It's just a well made lunch box. I don't use the inner partition as that's only really effective for dry foods. If I put anything wet in one section, the liquid would leak over to the other partition so I don't bother. I stopped using the band to secure the lunch box because the box is leak proof enough and I found it annoying having to remove the band every time. Very happy with this purchase and with the brand too - I'm looking to buy more of their products including their charcoal water bottle filter.
