These are often larger pins starting at 1.5 inch size and are typically more detailed and use soft enamel or hard enamel fills.
Soft enamel pins are the most common type of custom trading pins. When it comes to training pin manufacturing, soft enamel pins are what most people think of. Raised designs filled with enamel paint give these pins a specific look and feel.
Hard enamel pins are another good option for custom trading pins.

Offset printed pins are a faster and often more cost-effective way to make trading pins. Due to their manufacturing process, they are often more cost effective and can easily have high levels of detail
