Due to the handmade nature of enamel pins, they will not be 100% perfect. Sometimes pin grades will be grouped together (e.g. "standard/b-grade") for looser grading and convenience. Each pin is inspected and graded according to the general criteria below:STANDARD GRADE: Best pins in the batch! Minor to no flaws (can have minor scuffs, tiny specks, shallow enamel under-fill, etc.)B-GRADE: Small flaws (small marks, enamel nicks, scratches, enamel under-fill, etc.)C-GRADE/SECONDS GRADE: Flaws more visible than B-grades (enamel under-fill, enamel paint spills, small areas of missing enamel, wrong enamel color fill, discoloration, etc.). Not too major.SUPER SECONDS: Obvious, major flaws, worse than regular seconds (large or multiple areas of missing enamel, very visible smudges/discoloration, major dirt marks, very wobbly back-posts, major polishing issues, etc.). Greatly discounted; usually only sold in mystery bags.Pin grading is subjective. Pins will vary in flaws and may be more obvious than others. They are given at random within their respective grades; requests for "good" pins will not be honored. If you are worried about receiving a pin with more obvious flaws, please consider purchasing a standard quality/b-grade pin instead!
