It's a great brush and would give it a 5 star rating but the end of the brush doesn't fit in the bottle I have (too big of brush end)
10/10 will be purchase more products from Bamboo Switch in the future.
I had to force the brush into the opening of my Nalgene water bottle but once in it worked great
Bamboo Drinkware Cleaning Brush
Got this to replace another glass brush I got quite a few months ago elsewhere. I am so happy I got this from bamboo switch! It works like a dream, and even my partner loves using it. As usual bamboo switch proved to me they are the place to go!
