2005. Zippo tested the Iris PVD lighter in two separate pilot runs in October 2003 and January 2004. The lighter case was coated using a physical vapor deposition (PVD) process to produce the Iris finish. Failure to achieve acceptable colour during the pilot runs, resulted in termination of the Iris process after a run of 3600 pieces.
The Iris Zippo lighters were never sold at retail or featured in any Zippo catalogue. The remaining 993 lighters were exclusively offered to Zippo Click members.
