Every single one of these are independently made/custom pins. This listing lets you choose exactly which pin(s) you'd like. 

The shipping price is flat rate meaning that it will remain the same no matter how many pins you purchase. If you purchase 1 pin, you will pay $4.99 shipping. If you purchase 10 pins, you will pay $4.99 shipping. That is TOTAL shipping cost, not per pin. For example, if the cost of 10 pins is $100, then you will pay $104.99 for your order total. Buying multiple pins will save you a large amount on shipping.
