They don't pop open, the contents don't spill & they still look like the day I bought them (maybe 5+ years ago).

Questions

Will soup or curry leak into the bag?

Not when the seal is clean, seated in its channel and the clips are shut.

Can my child open it?

The clips are firm to keep the seal tight, so kindy-age children may need a hand.

Is it dishwasher safe?

Yes. Lift the seal out and wash it separately so it stays clean.

Can it go in the microwave?

No. Stainless steel can't go in the microwave. Warm the food first, then pack it.

Can I get a replacement seal?

Yes. Email info@mealsinsteel.nz with your box size and we'll sort one out.

Will it dent if it's dropped?

A hard drop can leave a small dent, but it keeps working for years.

Fantastic, Seals well and no plastic. Don't know about the ins and out of silicon but figure it's better than plastic.

Good lunchbox size

Hubby wanted something to fit his sandwiches as he kept breaking plastic containers so I got him this. . . .he loves it! It weighted lighter than what they said, which is good as he uses it for hiking/mountaineering work so likes his gear lightweight (ish). Clips are kid friendly for opening. Silicone looks quality.

Great quality

I was happy to see the lunchbox is very sturdy and the seal is clever so you don’t get leaks

Great quality - almost perfect square lunch box

Really happy with the quality, but the square containers don't stack neatly with the lids either on or off which does make for messy storage. Would be 5 stars and perfect stainless steel lunch boxes if they stacked inside each other with lids off, or at least could stack with the top of the lid matching with the base of the box above. Would still recommend for sure!

Hubby loves these

Great containers for a tradie husband. Tough and leak proof. Holds a good amount.

5 *

I have been using plastic containers for so long and I was over it. I looked into stainless steel and came up with meal in steel as I wanted something leakproof and the size suited me. It was the best purchase and I was able to buy with free shipping! I will be looking into a smaller snack box now too.

top-notch stainless steel that exudes durability and resilience.

I have been thoroughly impressed with its performance and design. The shiny exterior of the lunch box is not only aesthetically pleasing but also gives a sense of cleanliness and sophistication. The material feels robust and promises longevity, ensuring that this lunch box will be a reliable companion for many meals to come. The size of the lunch box is just right. One of the most remarkable features of this lunch box is its secure locking mechanism.

Great lunchbox option
