Boomwhackers Octavator Caps 8-Pack

They do the job & bring the bass!Saves you buying the bass set but you can't take them on a off easily mid-playing so probably still best to get the bass set, this is just a cheaper way to convert your existing set in the meantime.

These do not fit boomwhackers at all :(

Just what I wanted to extend the range of my boomwhackers without having to buy another set in lower octave. Use them at school and have enough to carry already so these are good.

they make the boomwhackers deeper in sound. The kids love playing with the boomwhackers and put the caps on to play about with the sounds they can make with them

Didn't fit the boom whacker set that was recommended with this product
