Can keep lunch warm

I have been looking for a bigger insulated lunch box for my high school son for a while. This one is a good fit. Wide opening and can hold enough for a teenager boy. I tested it by pouring hot water in the container. After 4-5 hours, the water was still very hot.

worth it!

It is bigger than I thought! I put water in and shook it, and the water didn't flow out. I thought it was a bit expensive, but I changed my mind as soon as I opened it. It's a good price range, based on the silicone on the lid and the durability of the bottle itself.

Highly recommend!

I recently purchased two insulated food containers from Mainstays — the 33 oz rectangular and the 28 oz round ones — and I'm really happy with them! Both containers are made of stainless steel and feel very sturdy and well-made. They keep my food warm for hours, which is perfect for busy days when I don't have time to reheat my meals. The lids seal tightly, so I don't have to worry about spills. I also love the sleek and simple design. Definitely worth the price. Highly recommend!
