The suturing threads have 3/8 circled, round 18mm reverse cutting needles to provide maximum strength and accuracy. The stainless steel curved needle comes with 75cm long poly propylene monofilament thread made from high quality material that resists repeated bending and ensures optional knot integrity. The needles are individually packed, sealed and sterilized. The 5” x 7” skin-like suture practicing pad is made in 3 layers to imitate skin, fat and muscle layers which is mounted on a plastic base for stability when handling. Multiple laceration types are imitated to ensure a unique practicing every time. Comes complete with an instruction manual.
