Special Rebound
There is four special elastics hold on rebound that lighten the pressure of the needle bar, working silence.

Medical Grade LG PC
The frame made by PC polycarbonate, Polycarbonate is colorless, transparent, heat resistant, impact resistant, flame retardant, BI grade, and has good mechanical properties at normal use temperatures.

Original Design
From the outer needle shell to the needle thread, and even every part, we have carried out layer screening and testing to make a needle run smoothly, save more ink, fast color, low skin loss, and every detail is critical.

Lowest Tin Solder    
The needles wire is fixed by fogging and discharging needles, plastic sets and precise moulds, which greatly reduces the welding process, thus avoiding the chemical pickling process and ensuring the safety and hygiene of each needle wire.

New Shell Design
The design of ink guide groove is added under the needles nozzle to increase ink storage. The protruding part becomes the track when the needles is out. With the arc clamp limiter on both sides of the needles nozzle, the friction coefficient is reduced, the stability of the needle is increased and the smooth needle and ink flow are guaranteed.
