Works great in the galon carboys you can get from Whole Foods that come with free apple juice inside.
Sorry, but I was sent the stopper by accident.
Works as it should and was delivered promptly
I'm making a jig for Woodturning and they are working great. The stoppers will hold a turned bowl so I can finish the bottom of it.
