Review: Great glass leftover storage containers! - I love this set! I just should have checked the sizes. I could use a few bigger glass containers. Great item! Very durable. The seal is really tight. You can take the leftovers right from the fridge in microwave them. They are very easy to clean. I throw them in the dishwasher. They have a stackable design. Review: Great containers, just don't micro with the lid on - I've had these since 2018 & not a single problem with them until now. I'm a bit shocked by all the bad reviews. I've used these in the dishwasher, the microwave, the freezer. I always next them for storage so Idk why people are saying you can't stack them. I haven't been particularly gentle with them or treated them like they're fragile. I've not seen a single shard of glass this whole time. I don't know if I got lucky or what, but I love these containers. Because I can nest them to store them, they all fit nicely in a drawer. They do a brilliant job of keeping food fresh. I've started chopping a lot of my veggies when I buy them & storing them ready to use in these because they keep & stay crisp so much longer. They can sometimes be hard to close or open, so be aware if you have weaker hand. My 10yr old needs help sometimes, though most of the time he can do it. I've sometimes had to turn it on it's side to get better leverage but it always does what I want it to. I've been really happy with these, I'm only back to see if I can find replacement lids. I put one in the microwave, with the lid offset so it wouldn't get stuck. Except, it slipped into place and got very, very stuck. This has happened once or twice before, but never this bad. It was so sucked in & tight to the edge that after twenty minutes of trying to wedge something in between the lid & edge to break the seal I gave up & stabbed the thing. Let the air out & I'm having my lunch but now I'm down a lid. lol That isn't the container's fault though, that was user error. ## Features - Includes Rectangle 1 x 6.3 cup plus 2 x 3.5 cup plus 1 x 1.6 cup Square 1 x 3.3 cup plus 1 x 1.5 cup Round 1 x 3.1 cup plus 1 x 1.6 cup plus 1 x 0.7 - Oven-safe and microwavable - Airtight and Leak-proof - BPA free and recyclable - Different sizes to meet your storage needs, 18 Pieces include 9 Containers and 9 Lids - Note: The glass containers are only microwave & oven safe.

It would melt in the oven. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00LN810PM | | Best Sellers Rank | #73,865 in Kitchen & Dining ( See Top 100 in Kitchen & Dining ) #1,947 in Food Container Sets | | Brand Name | Glasslock | | Capacity | 1000 Milliliters | | Closure Type | Snap | | Color | Clear | | Container Shape | Rectangular,Round | | Customer Reviews | 4.4 4.4 out of 5 stars (6,271) | | Global Trade Identification Number | 00848313000948 | | Is the item dishwasher safe? | Yes | | Is the item microwaveable? | Yes | | Item Dimensions L x W x H | 8.5"L x 6.5"W x 3.5"H | | Item Form | Set (Rectangular, Round) | | Item Type Name | Food Storage Containers | | Item Volume | 1000 Milliliters | | Item Weight | 10 Pounds | | Manufacturer | GLASSLOCK | | Material Features | Oven Safe, nan | | Material Type | Glass | | Material Type Free | BPA Free | | Other Special Features of the Product | Microwave Safe,Airtight,Leak-Resistant | | Package Quantity | 1 | | Product Care Instructions | Oven Safe | | Size | 18 Piece | | UPC | 885145555116 731642536137 735343598654 848313001648 791769547317 848313000948 190584119172 077925022318 782195436290 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Glasslock - **Capacity:** 1000 Milliliters - **Color:** Clear - **Material:** Glass - **Material Feature:** Oven Safe, nan ## Images ![Glasslock 18-Piece Assorted Oven Safe Container Set - Image 1](https://m.media-amazon.com/images/I/71yf9ldO1ML.jpg) ![Glasslock 18-Piece Assorted Oven Safe Container Set - Image 2](https://m.media-amazon.com/images/I/510yb2N-bML.jpg) ![Glasslock 18-Piece Assorted Oven Safe Container Set - Image 3](https://m.media-amazon.com/images/I/61L2HWPgeYL.jpg) ![Glasslock 18-Piece Assorted Oven Safe Container Set - Image 4](https://m.media-amazon.com/images/I/51+5oUUWaNL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Are they glass or plastic?** A: The containers are glass, and the covers are plastic. **Q: Please could someone tell me whether the plastic tops are BPA free? The box does not specify. Many thanks.** A: New info on BPA shows that the substitute chemical is not better and could even be worse. Do not heat the lids or any plastics on contact with food. **Q: Are the lids heat resistant? Can they be used in the microwave?** A: No! Regardless what the mfg says, the lifs will distort and the silicone gaskets will not seal. Keep this in mind for every product question whether it's your automobile manual that says you only need to change your oil every 7,500 or 10,000 miles (they want to sell you another car) or Snaplock lids (they want to sell more of those too) **Q: Does anyone know where these are made?** A: these glass lock are made in KOREA.its a wonderful container. well locked. Space saver, easy to clean, not expensive but looks like. in short, its a good deal. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great glass leftover storage containers! *by S***P on July 5, 2025* I love this set!

The variety of rectangular, square, and round containers makes it easy to portion out lunches and dinners for the week without feeling restricted by one uniform size. I especially appreciate being able to cook, store, and reheat all in the same glass container (without the lid), which reduces dishwashing and saves time. The clarity of the glass allows me to instantly identify what’s inside, helping me stay organized and avoid food waste. For structured weekly prep or simple leftover storage, it performs exceptionally well. Size | 5/5 The assortment of sizes is extremely practical. With larger 6.3-cup and 3.5-cup rectangles for family-sized dishes, mid-range squares for side dishes, and smaller round containers for sauces or snacks, the range covers nearly every typical kitchen need. I don’t find myself wishing for a different size because the set already anticipates common use cases. The nesting capability also makes cabinet storage efficient. Whether packing lunches, storing chopped produce, or refrigerating soups, the size variety feels deliberate and well-balanced. Leak proof | 4.5/5 The airtight, leak-proof seal is impressive. Once the polypropylene lids are snapped into place, the containers feel secure and dependable. I’ve stored soups and saucy dishes without worrying about spills in the fridge. The locking tabs provide a reassuring snap that indicates a tight seal. While I would not intentionally shake them upside down for extended periods, they handle normal storage and transport very well. The seal also helps maintain freshness longer, which is noticeable with leftovers and prepped ingredients. Sturdiness | 5/5 The tempered glass construction feels thick, solid, and durable. These containers do not feel fragile or flimsy; they have a reassuring weight that suggests long-term reliability. They transition well from refrigerator to microwave or oven (without lids) and clean up beautifully in the dishwasher. I have not experienced chipping or cracking with careful, normal use. The lids are flexible yet sturdy, and the locking tabs feel strong without being overly stiff. Overall, the build quality gives confidence that this set will last for years. Looks | 5/5 Visually, these containers are clean, modern, and minimalist. The transparent glass combined with the streamlined lids gives a polished, organized appearance inside the refrigerator. I enjoy opening the fridge and seeing neatly stacked, crystal-clear containers instead of mismatched plastic tubs. The design feels timeless and functional rather than trendy. They are attractive enough to bring directly from the fridge to the table when serving leftovers, which adds convenience and a cohesive look to meal presentation. Food capacity | 5/5 The total capacity across the nine containers is generous and well distributed. Larger containers easily hold full casseroles, pasta dishes, or batch-cooked proteins, while the smaller ones are perfect for fruit, dips, or portioned snacks. The depth of each container makes efficient use of fridge space without being awkwardly tall. I appreciate that the 6.3-cup size can handle substantial quantities, making it suitable for family meals. For a single set, it provides impressive flexibility and sufficient volume for a wide range of food storage needs.
