These wheels have cosmetic blemishes and may show small visual imperfections that do not affect performance. They are NOT covered by warranty, and do not come in Proto's retail packaging. The most common blemishes are tiny air bubbles or wrinkles on the edge of the urethane, but can also include scratches or dings on the anodized core, missing or smeared printing on the urethane, or crooked/incomplete laser engraving graphics on the core or stained/off-color urethane/core.
Blemishes are strictly cosmetic defects. These are simply not up to PROTO's "first-quality" wheel standard, but they will perform the same as any other PROTO wheel.
