Chromatic set of 5 to go with BOOM-BWDG (previous code PP790) boomwhackers as the equivalent sharps and flats in a full chromatic octave.
Boomwhackers are tuned percussion tubes, brightly coloured, affordable, easy to play and lots of fun.
Play them on a hard flat surface, hitting the floor with the whole length gives the loudest sound.
