Slightly faulty enamel pins!!
The pins might have some light scratches, slight discolouration or little spots. From afar they are hardly noticeable but they're not perfect.
** The prompto has some discolouration on his face like as if the enamel paint wasn't mixed properly
** The rose gold plating on cupid lance rubs off after 2 weeks and will look like the picture shown (rose gold lines turns black)
