yumbox presto leakproof stainless steel bento lunchbox review

When I consider the sustainable swaps our household has made, stainless steel has been a large part of the trades that have passed the test of time.

We have traded plastic pegs for stainless steel pegs.

Then there was swapping the plastic mixing bowls for stainless steel.

We have swapped Teflon-coated non-stick pans for stainless steel cooking pans.

Years ago we began to use stainless steel lunch boxes and have not looked back.

While our plastic Yumbox Original and Yumbox Panino still gets plenty of game time, hearing that Yumbox released a sparkling new stainless steel lunchbox bought an excited twinkle to my eye. 

When we had the opportunity to review the stainless steel Yumbox, we jumped at the chance. 

We were kindly gifted a Yumbox Presto for the purpose of our review. 

All opinions are our own and based on our experience with our new Yumbox Presto.

Yumbox Presto Unboxing

what is yumbox presto stainless bento steel lunchbox?

The Yumbox Presto is a more sustainable 5- compartment, bento-style lunch box with stainless steel tray designed for whole family. 

Yumbox Presto fits so many on go meals, or snacks. They are a great size for users of all ages. 

From being a ideal choice and great size for kids to active teens, Yumbox makes providing healthy meals while out and about simpler.

It is the Yumbox that we have known for years, only with a stainless steel food tray. 

The molded stainless steel tray

Yumbox has made the sustainable swap from a plastic tray to an 18/8 / 304 grade stainless steel bento molded tray made with food-safe materials.

The classic convenience of the pre-proportioned compartments carries through to the practical leakproof design Yumbox Presto.

The wells hold ideal portion sizes for lots of variety for young children, preschool – age children, preteens and adults.

The Yumbox Presto features five perfect size compartments including four deep wells plus one shallow treat or dip well with star embossment.

One feature that I am loving, at first sight, is the lack of wells for water to gather in after washing which has been something that has rattled my cage when cleaning the insert of the Yumbox Original. 

At first glance, it looks like the water will simply run off before being towel dried. 

No more small spaces to dry before storing.

The latch

It has an easy-to-open single latch design.

The convenient latch makes for simple opening. Mr 3 has been able to open the Presto since he was 2.

The lid

The outer plastic lid is ABS plastic (Acrylonitrile Butadiene Styrene) which is BPA-free, Phlahalates-free, food safe, CPSIA, FDA, and CE compliant.

A leakproof silicone seal lid seals all compartments. 

The meticulously designed silicone seal is the major factor to the leakproof construction.

And… this is something to get excited about. 

The food grade silicone seal features a single lip that seals each compartment.

No more thin tracks to dry or get crumbs out of like previous Yumbox bento designs. 


It is the best seal to wash and dry yet!

If you know, you know. 

The lid is secured with a single child-friendly, easy-open latch in the front centre of the lunchbox. 

Once unfastened the lid swings seamlessly on two hinges on the rear of the food tray. 

No lost lids happening here!

All Yumbox products undergo thorough safety testing, and compliance checks for utmost safety, and safety assurance.

is the yumbox presto heavy?

When compared to our other stainless steel lunchboxes, I would say that the Yumbox Presto is not as heavy as others around the same size. 

When I first opened the Presto, I was surprised to discover that the lid held more weight than the stainless steel food tray. 

However, having learned about the benefits of using ABS plastics, it is understandable that this hardwearing, durable material has a bit of weight in it.
