Food grade borosilicate glass is used for the sealing tank group, which is lead-free and non-toxic.
Are you find a truly airtight glass storage jar？ We upgraded our jar to a screw-top, which is more airtight than other lids.
This is a set of super cute spice jars. They are glass and come with both a wooden, screw-on, top and spoon, as well as an anti-slip rubber bottom you can put on or leave off.
The set of glass food jars includes some pre-printed label sand some reusable, write-on labels with the write-on marker. These will make a pleasing addition to any kitchen.
The kitchen containers for snacks or portion-controlled servings. Looks great！
