The staff pins from the Brazil Pavilion are truly difficult to obtain. They are not distributed to all staff members, but only to those chosen by their superiors. Furthermore, even from those staff members, the number of pins available for trading is limited, similar to a high-end watch store, and they are selective about who they give them to. It's said that it's nearly impossible to get one unless the staff member likes you. I am selling this pin as I am organizing my pin badge collection. Please feel free to contact me if you have any questions.
