Netsilk — Black Braided Silk
Medical-grade natural non-absorbable silk sutures engineered for superior knot security, tactile handling, and smooth tissue passage.
Netsilk — Non-Absorbable Silk Sutures
Netsilk is a natural non-absorbable, braided surgical suture composed of organic protein derived from Bombyx mori silkworm filaments. Coated uniformly with silicone or refined medical-grade wax, Netsilk provides minimal tissue drag, high tensile strength, and knot stability during complex surgical procedures.
