The largest jar measures 3 in by 2 and 1/2 in. The tallest container measures 3 in tall. The smallest container is a 1in by 1in 1/4 in. These are jars that have been collected by some elderly woman who didn't want to throw away this glass. I see this as a craft project or a pincushion project or a shower project. 33 small glass containers. All For One price.
