Packaging

1 ea in rigid mailer
Darkening/browning is common for pieces stored in a general room environment for an extended period of time (several months), due to organics pick-up. Verify product is kept sealed during storage.
  • Keep pieces sealed and protected from general exposure will reduce the effect. Recommend long term storage in air-tight bags.
  • Discoloration does not affect performance and can be removed by soaking in dilute nitric acid.
