Replacement needles for the ACLS-5 assessment. Includes 2 Perma Lok needles for the ACLS leather lace stitches and 1 large-eye needle for the linen thread stitch. This kit is replacement needles only. Leather, lace and thread not included in this kit. The Perma Lok needles are brass and the large-eye needle is steel, making them easy to clean and ideal for multi-user environments. The unique design means needles can be threaded in seconds. Additionally, Perma Lok needles feature a revolutionary, vice-like grip that ensures lacing won't slip out. While not a timed test, these needles allow for stronger, speedier lacing for the ACLS.
