Review on 🥣 Organize and Preserve with JoyFul: 24pc Borosilicate Glass Storage Containers with Lids - Airtight, Freezer Safe, and Stylish Solution for Food Storage, Pantry, and Meal Prep by Jessica Rae

So I didn't know they were made of spaceship glass :). They looked so beautiful in the photos I just had to have them without reading all the details. But take the time to read the description on the product page as there is a lot of good information there including the recommended temperatures (104 to 1040F) for example, pretty impressive I have to admit. The glass is really thick but very clean and smooth. The lids are BPA-free, so I don't have to worry. The four (4) flaps on each lid are very easy to open and close, snap in and out, and are very firm. The silicone seal is removable and works really well, I think it's filled with air inside like a small bike tube. Needless to say, the first thing I did was to do a reverse leak test as shown in the attached photos. Happy to report there were no leaks at all, not a single drop of water, obviously airtight. Overall I am very impressed with these 12 sealed containers, easy to use and clean and dishwasher safe by the way. Stackable with so many uses. Well packaged, between the layers and foam insulation, the whole thing came, nothing broke :).
