Often referred to as "standard" pins, a-grade pins are the highest quality pins that PenguChan Studios offers. These pins are free of major imperfections, but they may exhibit the following minor imperfections:

• Slightly low or uneven enamel fills
• Imperfections on the back or side of pin
• Superficial scratches or scuffs on metal or enamel surfaces
• Superficial specks, dots, or bubbles on enamel
• On Screen-Printed Pins: Slightly misaligned screen-printing
• On Glitter Pins: Varying flecks and/or small specks of stray glitter

The imperfections (if there are any) are only visible upon close inspection and/or looking at the pin under certain lighting or from a specific angle.

Often referred to as "seconds" pins, b-grade pins may exhibit one or more of the following defects:

• Noticeable flecks, dust, bubbles or "floating specs" in enamel
  
• Noticeable scratches or scuffs on metal / enamel surfaces
• Oxidization of the metal
• Low enamel fills in larger or visually important areas
• Noticeable smudges and/or staining on metal or enamel surfaces

The imperfections are visible upon quick inspection, but not from a distance. These pins are sold at a discount from their standard pricing.
