JDR New Arrival：Quartz 12 hole chromatic harmonica 

Why this chromatic harmonica doesn't stick to the valvas? Quartz 12 holes 48 tones chromatic harmonica only has a few valves attached to the inner side and removes some of the valves on the outside of reed plate. It uses new technology to adjust the gap to ensure air tightness, and maintains air intake and air output similar to a full-valves harmonica.
