Every single one of these is an officially licensed Jurassic Park/Universal Studios enamel pin. Each of these comes from the Jurassic Park Collector Pin boxes. 

This listing is setup with flat rate shipping meaning that the shipping price 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. So you'll save a ton on shipping by purchasing several pins from this listing.

I have photos available of the backs of every pin shown, as well as photos for size comparisons of each pin. If you'd like to see any of those photos, feel free to request them through messages.
