The Vic Firth Live Wires brushes have a little extra pizazz. Small round beads tip the end of each wire bristle, giving you an extra bite on any drum or cymbal you hit with them.
These brushes are fully retractable, maxing out at a 5" spread and sliding into a 0.53" protective rubber casing that is colored bright red so you know which ones you'll be pulling out of the stick bag.
