This is Focalink’s Satoshi Osawa Signature Ocarina in the key of Alto C from A to high F for a total of 13 notes. Focalink ODM this ocarina according to Mr. Satoshi Osawa’s tuning requests and after having got his approval, we release this Osawa i plastic ocarinas simultaneously with Prima Gakki of Japan to the ocarina world. The material ABS used is coincident with SGS standards of low toxic products There will be some molding lines showing up on the appearance of plastic ocarinas and similar traces on the plastic recorders as well. We have to use high temperature to melt ABS powder and use strong pressure to push the liquid ABS into the mold. Inside the mold, there are iron rods to create the spaces of the holes on the instrument. When the liquid ABS encounters the iron rods, they will split into different flows and meet again at the other side. Therefore, as it releases the hot air, traces will show up. As a result, there will be traces, not scratches or defects on the plastic ocarina.
