It varies from pin to pin, but its based off size, colors, thickness and features of a pin. also of course how busy the manufacturer can be. The longest pin can usually range from 6 to 8 months. This is not unusual for pin producers that maintain high quality standards. For example, smaller pins that have less then 8 colors and are simple are typically done faster then the design with multiple colors and add-ons, glitter, stained glass or pin on pin. The mold or "stamping" is done by hand or machine, then the pins are hand painted and filled with color. Next they are baked in an oven once cooled off they are sent off to be plated and printed.
