Does anyone else still buy bottle brushes to clean their travel coffee cups with?? One day I was doing the dishes and was about to try to shove my hand into the narrow opening of the cup with a sponge and saw the bottle brush sitting at the edge of the sink. It was on it's last leg so I decided to use it with the travel cup and it is perfect! I think Starbucks should make one so I don't have to buy bottle brushes anymore! Just thought I would share!
