Long Handled Narrow Neck Bottle Cleaning Brush 5 "Little brush with strong bristles" Mrs Kennedy 25 September 2018 I bought this brush as an addition to the large bottle brush. I wasn’t sure at the time how great the large brush would be... it’s fab! Anyway this brush has silicon bristles and is great for getting into twisting parts or screw tops on travel coffee mugs or children’s travel mugs. It retains it shape and is also good for small necked bottles. I’m pleased with it!
