The Ethicon 662H suture is a high-quality non-absorbable Nylon surgical suture. It measures 18in. in length, has a size of 4-0, and are dyed black to provide greater visibility while suturing. This suture comes with a FS-2 reverse cutting needle and has 36 sutures in a box.
I work with a university where we need a wide variety of suture for teaching and research. Happy to find a quality product. Ethicon is a great brand. Also happy to know that they have alternate brands available.
