Each package contains 2 Lil Hookey serger seam hooks that are nickel plated. These hooks make it quick and easy to lock serger seams. Simply snip the seam thread tails to 2 1/2 inches and insert the Hookey blade into the serger seam at least 1/2 inch from the end. Then, hook the thread tails near the ends and pull them into the seam by rotating the hook towards the fabric. Once the thread tails are secured, unhook and clip them. Made in the USA
