Seconds
From Melting Pot Wiki
Seconds are color rods that are not within the desired range of color. They are sold at a discount because of the imperfection in color. Often, seconds will also be irregular in shape and have an inconsistent diameter, similar to odds. Unfortunately, seconds have been known to behave in a manner that is not in line with their first quality counterparts. While a color that is off a bit is to be expected with seconds, a COE that is off or other variables can be frustrating.
