Greenour Bottle Cleaning Brush 2 pack Bottle Brush Long handle, Washing Weter Bottle ，Beer Bottle, Wine, Kombucha, Decanter, Narrow Neck Bottles

There are two bottle brushes in this pack. Only one fits into the neck of 12 oz bottles, and the way that the end is shaped, it doesn't even scrub the bottom of the bottle. To make it somewhat useful to me for the purposes of cleaning out the inside of 12 oz beer bottles, I had to bend the end over so some of the bristles would rub against the bottom of the bottle. Not a very well thought-out design. They will brush, but not fully without some modification.

Just what I wanted. Reaches to the bottom of the large thermos my husband carries each day. There was two in the purchase which I also appreciated. As a bird watcher I also needed the second one to keep tube feeders clean. The bristles are stiff enough to do the job well but won't scratch things.

I got these brushes to clean my Contigo tumblers and they work very well. Do exactly what they're supposed to do and clean all of my units very well and easily. Can't ask more then that!

I use it for a glass bottle and the one is good for glasses that have a wide mouth - the other fits into my bottle with a small mouth but doesn't flair enough at the end to really clean the bottom of the bottle.

these work well to get the job done but you can’t effectively get close to the mouth of the bottle clean it it is a flat top bottle like an animal feeder bottle.

I used one for my bottle and one for my baby's bottle. They work great! I can tell they will last for a long time. Great product with such a low price

It's very poor quality. The bristles shed and stab your fingers if they accidentally touch them.

A little more flexible than I would have preferred, but it gets the bottles clean.
