Grading: 

Pins are all handmade items and may have some imperfections. If it requires you to take a photo at night zoom and intense scrutiny, it’s likely not considered a flaw.

• B: Some minor flaws that cannot be seen at arm’s length. 
• C: more obvious flaws such as deep pin pricks/marks, mostly surface marks on the arm when tilting under light (see last photo)
