SSNO220, but there's one that was made differently. The SSNO220 and JIS markings are in different positions. Thank you. I've tested it by blowing air through it, and it produces a sound. I haven't put my mouth on it. There's no case for one of them; it has cracks, scratches, and a name on it. I've cleaned it with anhydrous ethanol. What do you think of this item?
