The price includes a fingering chart, thumb-rest, joint grease, and vinyl pouch.
A key over the lowest tone-hole of the longer sized whistles allows small hands to easier reach the lowest tone-hole. Players often need one or more keys on longer low-octave models.
We can mount a key over any tone-hole of the -M- and -L- series whistles. The extra cost is $25.00 per key.
