These pins are just like all the others except they all have some slight imperfections. Some are more noticeable than others. All pins are hard enamel.
B-Grades are classified as barely noticeable and C-Grades are the most visible imperfections. This chart is a simple way to describe how imperfect each grade is for each type of pin.
|   | 
B-Grade | 
C-Grade | 
| Rifter | 
 Teeny dent on top of one ear / Very slight overfill on some lines 
 | 
Inks outside of the design | 
| Zelion | 
Slight damage and scratches to horn and face | 
Inks outside of the design / Teeth and horn not colored correctly | 
| Elders Set | 
Very slight underfill on Order's eyes / Some scruffs on the metal | 
 | 
| Overgrowth | 
Small scratches across the metal and inks / Tiny black in dots on petals | 
Larger black ink spots on some petals | 
There are very limited amounts for each one and they all vary in their imperfections. So unless you want one with a specific imperfection, the one you will receive will be random from the grade you choose.
