These particular Ultra Light DX Polecat factory seconds were not factory weighed, so no weight is listed below. They will mostly be between 100-125g.
Factory Seconds - Factory seconds are discs which during the quality control process post-production were deemed to have cosmetic flaws which affect the appearance or perceived quality of the disc, but which were not deemed to affect the flight characteristics of the disc (those discs are rejected entirely and destroyed).
Note: the image is of a regular Polecat and not a factory second.
