OXO Good Grips 4-Piece Smart Seal Leakproof Mini Glass AirtightContainer Set

Love everything about these! Healthy and safe storage for food. Stackable with lids on and nest for storage. Oven, freezer, microwave and dishwasher safe. Sealing gaskets are easily removable for cleaning. Will buy more. Hope to find larger sizes too.

I love these. They're small, but it's the perfect size for me. It is exactly as described and 100% airtight!

Be aware that the "4-piece" mini glass set is in fact ... 2 containers and 2 lids. Sure, that makes 4 pieces total but I think many people (including me) would assume it is 4 containers-with-lids. Actual product seems good.

4 stars for size not quality. These are the smallest food storage containers i’ve seen in my life. Pictures for reference.

Update 3 years later: We have eight sets of these now, all eight nested and neatly lined up in a drawer. One lid has broken, and one container has a little chip under the outside edge of its lip. They've held up remarkably well. I have exactly enough space in the drawer for one more set, and since we were just a little short for storing holiday leftovers, I came back to buy another set. I was happy to see it had been three years since we bought these. I bought one set of these to test before buying enough to replace all of our plasticware. So far, they have passed all of our initial tests. Over the next week, we'll learn more about freezing and overall durability. I am wondering what all these people are doing who are breaking these. The first thing we did was accidentally send half of these flying across the kitchen. They bounced off the granite countertop and slid over the edge and onto our stone tile floor. Three pieces. None of them broke. I'm going to do some hot and cold experiments and stress test this set over the next week to see if they become weaker and less durable. If they don't hold up, we'll toss them out and look for another brand, but so far, these are looking pretty darn tough. We sealed them up with colored water (food coloring) and shook them all around, put them in the fridge, shook them all around again, put them in the freezer, shook them around, let them come back to room temperature, shook them all around. Put them in the over for 5 minutes at 350, then took them out and shook them all around. No spillage. We put some tissue inside them and sunk them in a sink full of water, then swished them all around. No water got into the containers. The tissues were completely dry when we pulled them out and opened them back up. No leakage. So far, so good. Over the next few weeks or months, if these seem to break or chip more easily than my other tempered glass kitchenware, then I'll post an update at that time. So far, though, these seem very tough, very airtight, and very easy to use. The only thing I'll say is that it can sometimes be difficult to snap them all closed, but that is the price to be paid for no leakage. Update: Just wanted to add a tip. After having these for a month or two, I've figured out how to consistently get them closed with ease. If I'm having to apply too much pressure to close the lid, I just unsnap and re-situate the lid back onto the container. It will close with ease every time.

Very useful for meal prep and carrying condiments.

These small OXO Good Grip containers are just right for storing little portions. The lids are easy to snap in place. The containers are strong and manageable. They have proven to be airtight so I use them to keep the last of my guacamole fresh for the next day. They can be stacked on top of each other to save room in my refrigerator. Good Grips were a lucky find.

Surprisingly small. Don't need to toss them into a lunch box. I bought a different brand for half the price and twice as many containers.
