Yes, these are labeled as dishwasher safe, and I feel they are top-rack safe. There is a little bit of a bend after the dry cycle, but once the pieces are stacked, they straighten out. Looking at the price, ~$20 for 45 containers and 45 lids is about 45 cents per set. I don't think you can even get similar at the dollar store for even close. I do wish the containers were a little smaller. Other than meal prep, one of the reasons I bought these is to tuck in my bag when eating out, as about 90% of the time I bring home leftovers and I detest Styrofoam and single-use containers. The two-compartment container will work great for "doggy bag" purposes. If you want something that won't react to tomato sauce, or to heat, and last a long time, you might want glass storage containers with snap lids, but you'll pay a lot more for those. I think these are a nice middle ground. The set is large, so I'm using some and leaving some in the box to rotate in as needed. I really like these for gifting foods to friends. It's no big deal, like 50 cents, if you don't get your container back, and they do look nice.

Bought this set for meal-prepping and to generally make fridge organization a lot easier. I love this set very much and use them every day for storing leftovers in addition to prepping. In fact, I used a couple of these guys yesterday for a picnic we went on! They are dishwasher safe but not with the heat setting so we often hand wash these instead or turn off the heat setting when we do use it. Stack easily and don't take up too much space. I'm a fan :)

Be careful, these containers are thin, and d tops are very fragile. 3rd use and I already have a broken top. Prayerfully all of them will not follow suit. I sent a set to my sister as well and hope Sams Club doesn't embarrass me with a cheap gift. Just want everyone to know what they are getting.

Was very lucky to get these for$8 a box not that long ago. Bought 4 boxes .

Very cheap plastic

Love the idea ... all the same size, compartmentalized meal prep. Dishwasher safe, freezer safe, microwave safe. However, I put the first one in the dishwasher, top shelf, and it is already warped. Disappointing.

I bought this through Sam’s club and when I opened it, it was missing 5 lids. Sam's is unwilling to except the return and they are out of stock. I would recommend whoever packages these up learns to count.

I bought these for my 5 year old's snacks for school.They hold up so well, and they are easy for him to open and close on his own. They do not leak and are pretty durable. I would buy these again!

I was excited to use theses. However, they leak😡 so you won’t let me post a review because it says it’s to short. This is my review title The lids do not sit tight and it leaks

I recently purchased several sets of the meal prep containers. My family enjoys using these containers for lunch and dinner. They provide the perfect size to control your food portions!
