Key product features
- High quality bulb for most Acme whistles and calls
- Hygienic method of playing whistles
- Good quality materials throughout
This is a very handy item. It essentially fixes to the end of a range of Acme whistles and negates the need for anyone to actually blow them. By squeezing the bulb, air is forced down the whistle and a sound is produced. It is much more hygienic for the school percussion section!
