Item says it is oven safe and microwaveable. I put it in the microwave and it completely cracked in half. Not safe in microwave so probably not safe in oven.

Great storage containers. No issues after owning previous sets for at least 5 years, many that are used daily. We wash the lids and bases in the dishwasher. I highly recommend.

The glass does shatter! I placed the square container in the microwave, no lid, for 60 seconds. The glass shattered. I do have photos, not truthful in the description.

[This review was collected as part of a promotion.] Member's Mark 24-Piece Glass Food Storage Set by Glasslock can also be used to cook in! Yes. I was absolutely pleasantly surprised coming across this set. I love the glass with secure, locking lids, being useful in multiple ways. Easy for storage use. Great for cooking in. Oven safe, microwave safe, dishwasher safe, freezer safe. There’s simple clean up with little to no scrubbing required, and maybe even best yet, because these containers are glass, they won’t stain or absorb undesirable odors! If I accidentally drop one of these containers, they’re specially made with tempered glass, making them shatterproof. Yet another amazing feature to this set. I certainly intend to purchase another set or two. I couldn’t ask for better in a set of containers!

[This review was collected as part of a promotion.] These are good glass containers for the price. The durability is tough. From cold to hot. I didn’t see any cracking or chipping. The storage container size and capacity held lunches snacks and dinners. The different sizes were great. Easy to clean. The clips that secure the lid seem annoying but help ensure the lid is on tight on the container. I also looked at the prices and these are great for the price.

[This review was collected as part of a promotion.] I can’t tell you how excited I was to finally replace my plastic food storage containers with glass!! These are beautiful, well made, and stack nicely. They are easy to wash and the varied sizes are great for any amount of leftovers. The glass makes me feel healthier and I appreciate that they are microwave and dishwasher safe. Not to mention, the blue lids are so cute! I recommend this product.

[This review was collected as part of a promotion.] I exclusively use glass containers because they are more durable and healthier for my family. These containers are heavy due to their thick glass material. They appear to be well-built. I've been using them in my air fryer and oven and enjoy the ability to store them in the fridge or freezer. These containers are simple to clean, whether by hand or in the dishwasher. My favorite future feature is the ability to store them within each other to conserve space in my pantry.

[This review was collected as part of a promotion.] A great set at an even better price point. 12 glass containers, and they look great! The quality is spot on. Lids secure well and don’t absorb smells. They stack nicely making for easy storage. I quickly tossed all my plastics and replaced with this beautiful set!

[This review was collected as part of a promotion.] The Member's Mark 24-Piece Glass Food Storage Set by Glasslock impresses with its versatility, offering a variety of container sizes suitable for meal prep, leftovers, and pantry storage. The design is clean, modern, with airtight, leak-proof lids that snap on securely — ideal for both fridge and freezer use. Cleaning is easy, thanks to the smooth glass surfaces and dishwasher-safe materials, though lids may require hand washing to prolong their seal integrity. The durability is notable; the tempered glass resists stains and odors and feels solid, though the containers are a bit heavy compared to plastic options. In terms of storage capacity, the range of sizes works well for both small portions and larger meals, and they nest nicely when empty, though stacking with lids on may take up more space. Overall, a reliable, high-quality glass storage set if you don't mind the extra weight.

[This review was collected as part of a promotion.] I love this food storage set!! This set comes in all sizes…no matter how small the leftovers might be. The containers are made of glass and have a decent amount of weight to it. The snap on lids are the best!! Four snaps and it’s sealed!
