Reviews

Awesome food containers

"I bought my first 50 oz container, at the food coop in Ashland Oregon maybe 30 years ago for something like 20. I thought that was a lot for a food storage container, but I still have it and have been using it all these years later. Meanwhile I have purchased several more of different sizes. We love these containers because there's no toxic plastic touching our food, they are easy peasy to clean and they stack for consolidated storage. Simply awesome!"

This was a reorder!

"I've had my first few U-Konserve containers for several years. Great product. Now it is time to replace the additional plastic containers I've used with a complete supply of U-K's excellent supply of stainless containers for leftovers. NO MORE PLASTIC!"

I am gradually transitioning from

"I am gradually transitioning from my 30-year-old plastic food storage containers to U-Konserve containers. I like the way they store compactly, and the steel containers are dishwasher safe. I wash the lids by hand, which might seem like a negative, but they are very easy to clean thoroughly. Nice product. Next I'll buy some 50-ounce containers."

Perfect Seal & Size!

"Sometimes ya just need a lil container for a small amount of leftovers or a lunch sandwich. This is it! Keeps everything tight, fresh and cold. Silicone lid fits perfectly into groove and burps perfectly by popping the tab just enough to release extra air. Hoping the stainless stands the test of time. I will only use silicone utensils to remove food, so as not to scratch the surface. ANY scratched stainless will cause rust on any stainless you own. Avoid that by not scracthing the surface. If 6 months goes by with no rust, I'll be adding to my collection!"

Plastic Free

"I love these containers. I have purchased at least a dozen. I give them as gifts to family & friends to safely store food. They make great lunch containers and are especially good to use in a restaurant instead of asking for a "doggie bag. " the silicone lid seals tightly and the stainless steel is indestructible. ."

"Finally a To-Go Food Storage container I can show off and not be embarrassed by. I am super happy with this purchase. Like I said in my previous review there is a lot to love about these containers. Easy to clean, they stack, you can easily see what's in them, low profile lid is secure. Brilliant."
