A few of these are official pins but most are independently made. This listing allows you to choose exactly which pins you'd like to buy. It has flat rate shipping, meaning no matter how many pins you purchase, the shipping cost stays at $4.99 (For example: Buy 1 pin, pay $4.99 shipping. Buy 20 pins, still just pay a total of $4.99 for shipping. For example, if 20 pins costs $100 then your order total will be $104.99). I have pictures available showing size comparisons of every pin, as well as photos of the backs of every pin. If you'd like to see any of those photos, feel free to message me requesting them.
