This is a set of Tin Whistles (6 holes) Susato a very good price / quality ratio. A beak and 4 interchangeable Tunable body (Eb tone, Re, Do, Sib). Compared to Susatos "classic" black, Oriole these models have a sound a little more "Soft", slightly less powerful and less strident octave. Visually plastic is brown and dull, and go better in some circles (can go for a wooden flute in a medieval festival for example). In short, practical, lightweight, playable, good sound, good investment for any player trad Irish or Breton or else! (Careful, body and beak Susatos not compatible with "classic", the length of the nose portion Oriole being shorter and the diameter of a smaller body chouille).
