No. 6.5 Stopper - Solid

It works

... I don't know what to write about it. It seals for a 6.5 gallon carboy... It's got a hole in it. Fits any run off the mill bubbler..

It's a good stopper

There, I reviewed it. Can you stop sending me emails now?

Good way to close the hole

Its a stopper and it works good. I will say that I prefer the universal stoppers. The universal stoppers are larger and have more surface area to handle.
