Please note that this is a curved structure，the fingers are comfortable and not prone to problems. （to remind you not to buy a mid tone flute with a straight arrangement structure，because there are design defects in the straight arrangement midrange flute，the keys are not easy to be sensitive，and mats is easy to be misplaced.）
>Silver plating function:
1: Silver plated special copper tube，excellent resonance effect，longer residual sound，clear tone.
2: Full silver plating process，more bright appearance，soft color，longer use time，avoid nickel allergy.
3: The pipe body of the flute head adopts French taper. The nozzle is cut by automatic numerical control equipment. The size is very accurate and the penetration is strong，which makes the air flow more concentrated. Each head is adjusted and tested by a master with 30 years of experience
4: The original stainless steel needle spring has strong elasticity and is not easy to deform. The button rebounds quickly and feels comfortable.
5: Special sheep intestines leather pad，good sealing，only need to tap can achieve good sealing effect，reduce the intensity of playing
6: The broaching hole adopts automatic numerical control，and the position error of each voice hole is controlled within 0.02mm
Three technologies:
1: Digital hole technology，accurate hole position，improve pitch.
2: Double liquid quenching process，pipe material structure uniform，excellent resonance，excellent sound transmission.
3: Inner wall fine grinding technology，smooth inner wall，reduce air loss，play a greater role.
