Ultra-Pure Trombone Mini-mist gives around 70 sprays on a single fill.
Hold it in your hand and pump the mister with your thumb.
Gives a perfect, light mist spray and is not adjustable to a stream (teacher friendly!) 10ml capacity.
A perfect little mister!
Just fill with water and use to spray a fine mist on the trombone slide. When water is applied to a well-lubricated slide, it usually glides easier.
