This is a duplicate of a nice little wooden one I own that produces pleasant notes. It contains two depressions on the back for thumbs, or for a place to drill holes for two more notes, making it a 9 hole ocarina. Not yet sure the lowest note is C, but it should be in tune with itself as the volume and hole sizes are identical with my wooden model. Big question is... will the porosity of "Strong White & Flexible" keep it from working? Answer... way too porous to function. It will require stain and sealing to function.
