Great organized lunch box
Great organized lunch box.
I love this hardy metal tin! I started driving big buses for the city and I put everything I should eat in this container. I line the tin with wax paper and put in my peeled oranges. Sliced hard boiled eggs, Lovely sandwich pieces and other smaller items that are better for me than a bag of chips! It forces me to use portion size that are healthy too. Now It’s a nostalgic experience and all out delight to have a Lunch that celebrates me

Fantastic for sandwiches and so much more
When I purchased this container it was a little bit of an impulse buy, but it is an impulse buy that I absolutely do not regret. It's a great container for all kinds of food and events.

We’re kind of obsessed tbh
I originally ordered these for my daughter last school year, but we loved them so much I ordered for my son too. They are nearly indestructible, super easy to clean and hold a ton. Two fit in their lunchboxes, and are perfect for salads or sandwiches or snacks/fruit. Could not be happier with these purchases!

Love this box! Glad I got the GIANT one
Love this box! Glad I got the GIANT as it was not really that big! Box is stainless steel and so shiny, sturdy and well made. Have used it multiple times already. I use the tiny box to store boiled eggs.

Love these!
Just got 2 Splash Box XL to use in the freezer. The silicone lids are nice and pliable, even when cold. Much better than the brittle, cracking plastic lids on our existing fleet of containers. We will continue to upgrade to more of these over time. Thanks for making such a nice product!

Useful land fantastic container
Love how light these containers are compared to glass. I have just ordered more this time. I have had some others for a few years and they are like new even though we use them all the time. Great that I can put them in the dishwasher! They are pricey so I try to pick them up when there is a sale and I give them as gifts too! Also love that when food is still hot these can be filled, it’s not good to do that with plastic.

Practically perfect containers!
I have used these containers for the last 6 years or so. My daughter brought them to school for snacks and lunches. They have held up incredibly well. I bought these for my nephew entering preschool soon. LOVE that they nest, or can be used individually. We use them on day trips for snacks. And as you eat, you magically have room for trinkets to bring home. They are not microwaveable - so when bringing leftovers to work, you need a plate to reheat them. That is my only issue. Seriously, practically perfect containers!

Perfect
These containers are the best. I've been using my original set of 3 for years - and they are still going strong! Ordered more recently as you can never have enough. Love that they are plastic-free, lightweight, and I haven't ever had issues with leaking.

Practical and easy to use/reuse boxes
I'm delighted that I found your stainless steel lunch boxes and containers. At last I can give up "compostible" sandwich bags which are not safe and not really compostible in residential compost piles. Thanks so much for this wonderful alternative.

Great product
This is exactly what I was looking for for my kids lunches. No plastic, can be refused indefinitely and will eventually be thrown in the recycling bin if that time ever comes. Great product, thanks!
