Progressive Prepworks Thinstore Collapsible Prep/Storage Bowls with Lids - Set of 3, Dark Pastels

They are of "medium" thickness. Doesn't look like you can microwave them for a long time which is Okay with me but just wanted to share that as an FYI. They make great storage bowls (2 options of storage per bowl - you can fully extend for full use or partially extend) plus they collapse easily. The lids are easy to put on and stay there. Not sure if they are "spill proof" as I've not tested it for that. I don't like a lot of clutter & so I love the ease of collapsing them for storage plus they hold up great. The lids are very easy to put on and stay there. At times, I don't have a lot of strength due to neck issues & these are a dream, utilization-wise. I've tried the ones with the "snapping" lids but the issue with those is that within a few months, some of the prongs "snapped" off. I tried the more expensive ones, "Joseph Joseph" and initially, I was delighted with them. However, over just a couple of months, some of them warped and so the lids didn't sync with the container & so that was a waste of money. From now on, these are my go-to. I gave it 4 stars for durability as I can't see it lasting for years on end. But, we'll see. :)

I purchased these to travel to Italy with and I could not be more happy. We have a 2.5 year old and eating late meant he fell asleep or just wasn't hungry from all the delicious snacking we had been doing all day. Its not customary to have to go containers (except for pizza) in Italy so when the waiter left I slipped his food into the bowls. When he woke or wanted a snack we had the left overs. It was a great saver. The dont take up much space and are lightweight. The lids hold well and we did not having any spills. We also used this to split snacks between our friends children we were traveling with.

The quality is great and sturdy, but smaller than I expected. Make sure to get your measuring tape out. I placed a can of beer in the largest bowl for size reference.

These bowls are great. I originally bought this set 4 years ago for a camping trip, but since then, I've used them for many other purposes. They are great travel dog bowls for a hike or long trip.PROS: - They are compact and easy to pack. - They're extremely sturdy -- not a flimsy, malleable plastic that would collapse while you're using it. You'd have to put some force on it to collapse it back down. - They're dishwasher safe.CONS: - As other reviewers have mentioned, the lids need improvement. They are not airtight. I wouldn't use them for transporting any liquids.If you're looking for travel bowls for you or your pet or even a container to store solid foods, you'll love this set! If you're looking for general purpose containers to store and transport food, you might want to wait for a model with an improved lid design.

Purchased these bowls for my daughter so she could take canned soups and chili to school for lunch. She has a lot of books and other things she has to lug around so something to save space was crucial. These worked perfectly. They took up very little room, are microwavable safe and didn't collapse on her while eating out of them. As other folks have mentioned, they do stain pretty easily but that didn't bother us at all.

Love that they are collapsible, great for camping, space saving, great sizes.

We bought these because we thought they would be a great space saver in our travel trailer. When they arrived I was quickly disappointed in the size. The product itself seems nice. Collapses well, seems sturdy, and good quality. However, these are so small they aren't useful as "mixing bowls" the middle one is about the size of a cereal bowl. Good for small food storage, but can't be used for mixing anything.

And I still use them when going camping. Quality is so great, it's still sturdy even after so many years of using it.

Los amo!!! Cargo los 3 y son perfectos para cuando me sobra comida o pido comida para llevar o en otras ovaciones me llevo comida de mi casa y luego los guardo fácilmente, lo único malo es que guardan olores y manchas son geniales pero solo para trasportar comida no para guardarla ahí por mucho tiempo y lavarlos lo más rápido posible cuando los acabas de usar así no hay olores ni manchas :)

Fantastic when space is limited.Bought these for my husband to throw into his work bag. This work doesnt provide anything for dishes and the lunch facilities vary based on where in the building he is working - there is always hot water available but sometimes he has access to a microwave and fridge. He always carries at least instant ramen and canned soup but needed a bowl that could work for either, without takin up a ton of space so these are perfect. They can be used in microwave or with just hot water and fold uup to 1/3 thier thickness.I'm thinking of getting a second set for use in our travel trainer.

Got a good deal. very useful product. Very handy and space saving. Some reviews on amazon.com say it leaks if too much liquid in there. I have not used it to store a very liquid item. Mostly dry stuff or semi-dry stuff and it hasn't given me any problem so far.

Haven't used these yet but I have brought them for camping

Good quality, they take up less room for storing, love them for campingI don’t know about leak proof, the lids fit nicely but haven’t tried them to see if they are leak proof.
