● Molten electronic whistle, 3 pieces (used) in red, blue, and yellow

This is a set of three used molten electronic whistles (RA0010) in red, blue, and yellow. The batteries have just been replaced and they are ready to use. They were used by students in a girls' volleyball team's matches.

Because they can be sounded with a single finger without being put in the mouth, they are hygienic and used in a wide range of situations, including Judgement, sports coaching, and crime prevention patrols.
