Boy will this beautiful bottle brush get in the cracks for you.  Cleaning baby bottles, jars, tubing, hummingbird feeders, bathroom sink drains, and even a bong, the tip is soft and furry to fit in any crack.  The bristles are moderately stiff, and the twisted metal handle can be bent to reach and clean those hard-to-get spaces!  14″ long, covered with plastic sleeve,  and has a loop for hanging.
