OXO Smart Seal 12 Piece Glass Set

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.

Full stars but notice the size. Most of these are so small they are only practical for dipping sauces or whatever.

If you’re like me, you’re very familiar and happy with OXO products. I was excited to get this set in an effort to make my kitchen more environment-friendly by reducing plastic. I have two things to share with prospective buyers: 1) the lids take a little bit of effort to snap them shut. I’ve even had a couple “pop” open on their own. I just got these so I’m not sure if it’s a design flaw or I just didn’t snap them shut enough. Also, be sure to wash these in warm soapy water before your first use–don’t just rinse them out–because they seem to arrive with some kind of slippery film. I assume it’s to keep them nice during shipping. I had to wash them with Dawn to get them “squeaky” clean. I gave these 3 stars for cleaning because the grooves on the lids where the gaskets sit can trap grease and food if you don’t clean them well.

UPDATE AFTER SEVERAL USES: 1) The lids are easier to snap shut after realizing one needs to apply some pressure to the gaskets. The four tabs to clamp the lids down form a very tight seal–these will NOT leak! 2) I realized the green gaskets ARE removable, making them and the grooves easy to clean–5 stars instead of 3.

Es vidrio de buena calidad, puedes pasar las cosas de refrigerador al horno de microondas sin problemas. Las tapas sellan a la perfección y permite quitar los sellos con mucha facilidad para mejorar la limpieza, el tamaño es bueno para almacenar. Yo lo uso para llevar comida y ya no hay más derrames.

Really great buy!

OXO Good Grips Smart Seal Container 12 Piece Glass Container Set,Clear: These are the best containers I have found that are glass, yet with a leak-proof lid. My favorite size is the 8-cup size. This 6-container size (with 6 lids) has very small containers. I was not careful enough to check capacity. The most useful will be the 3 1/2 cup size. There is one that ais 1.6 cup, and two that are 1 cup, and 2 that are 1/4 cup. Those smaller ones are pretty tiny, and I am not sure I will ever use any that small. I was surprised by the tiny sizes because they looked larger in the photos.
I have been adding more of these to my kitchen so I can get rid of my plastic containers. My favorite size is the 8 cup. i will buy more of the 3 1/2 cup size.

From the research I did the type
Of glass these use is on of the safer ones. Good quality, dishwasher and oven safe.
