Original manufacturer's packaging may show signs of wear such as scuffs, tears, labels, markings, tape residue, dust, or discoloration. In some cases, items may be repackaged for storage or shipping purposes.

While the external packaging may not be in perfect condition, the part itself remains new and unused unless otherwise stated in the listing.
