Bernette Looper Threading Wire B62/b64/b68

This is a Bernina Bernette original looper threader wire. It is used to thread hard to thread threads through the loopers when the air threading will not work. Slide the wire through the looper pipe leaving the loop out and slide your thread into it. Then pull the thread through and "presto", your serger looper is threaded and ready to serge. Great when using wooly nylon thread and other specialty threads.
