It's Murphy's law. Put the needles in an envelope and put aside and use others. In a dew days they may work again. That's what heppens to me, electric things, electronic things, anything that won't work, I put aside. It might be the devil coming to steal your JOY! Anyway if it doesn't work after a few days or weeks, give away or throw aqway. Don't let it steal your JOY for anything. STUFF happens. (Do not follow this rule for eggs or things that are perishable.)
