4.5" diameter food-grade plastic funnel fits beer bottles or flasks.
It would hold water better if it didn't have a hole in the bottom ;-)
As a Funnel, it works well
I am please with my purchase of this funnel. It worked well. The small end doesn’t fit very far down into the 16oz sling top bottles, but it does fit and does the job.
It’s a funnel... it does what it’s supposed to. Not much more feedback that can be given on the item.
Bought this for brewing beer just in case ... use it all the time for kombucha!
