To be honest, this was an impulsive buy. I buy baby bottle brushes to use for cleaning my Klean Kanteen bottles. Mine is a Classic Insulated 20oz, it is a bit tall and has a narrow opening which makes it difficult to clean, which is why I buy baby bottle brushes. This brush is waaaaay out of my budget. This is really expensive but after a long time of searching the best brush for my KK, this brush is definitely worth the wait. It reaches the bottom part, cleans the sides, and it does not scratch the insides of the bottle. If you have extra in your budget, go and purchase this brush. It’s perfect for cleaning your Klean Kanteen.

I got this with the intention of using it on my plastic water containers. Gotta admit it's a bit pricey for a brush, but I like it. It comes with a stand and has a nice design and look to it. It also does a good job of cleaning. There's a smaller brush inside that you can use to clean tighter areas like mouth piece and lid ridges. If you have the budget, this is a good purchase!
