Metal Toothed Separating
Metal toothed zippers are made out of aluminum, brass, pot metal, titanium. Metal zippers used to be the strongest zippers available, but not any more. Just like EVERY zipper, there are good ones & cheap ones!
I have picked these zippers for the quality! But all zippers wear out! Metal zippers always can use a little help. Use beeswax to keep them running well: a candle, or Burt's Bees lip balm, or a product made specifically for zippers. Rub a bit on the open teeth, then open & close the zipper a couple of times.
