The new generation of contouring needles have been specially developed to minimize skin damage during injection procedures.JBP Nano Needle Advantages• Reduction of bleeding during procedures• Less pain - less stress for the patient• Increased inner diameter for the introduction of dense fillers• Ultra-thin walls and micro-polishing of the surface outside and inside the nano-cannulaFor perfect injections and pain relief ...1. Ultra-thin nano-cannula walls with widened inner diameter help to inject with less tissue resistance2. The production uses the most modern technologies of surface micro-polishing.3. The trocar needle is designed to reduce pain and tissue damage7 different standard sizes of nano-needles (length, diameter and internal calibration) are carefully adapted to specific doctor's tasks, different injection zones, their direction and depthThe package contains 24 pieces
