I've been using a cap with a horizontal handle, but they are no longer available. This is an excellent alternative.
Great cap for medium sized bongs!
Works well, well made! Look forward to years of happy times ! ;-)
It works as a dab tool and it fit my 14mm ****** quite well. The carb cap feature added a nice oxygen blend while pulling. Only drawback would be it's not an easy clean but I don't think that is worth a star.
