I'm a glass blower and these are amazing for my mini marble jars. They make a great fit and are just perfect!!

The cork stoppers are nice enough, but I wanted to use them for my Erlenmeyer flasks, which take a #6 stopper. This are identified as size 6 and since there are no actual size measurements provided, I assumed these would fit, but they are way too small.
