It is a very good 'long' B1 (soprano / sopranino) Rotter ocarina (10 holes). No apparent or evident 'flaws', just a little bit 'conventional', I mean, no particular or special 'strengths'. But also no weaknesses and that is a very good point in itself. It is quite loud (of course), suitable for outdoor exhibitions. I am quite satisfied with the ocarina, especially because the tone is solid and bright, but not annoying. A very good, little and handy, musical instrument.
