The back of the pin has three small boxes near the bottom. The first box has the Disney trademark and Made in China in two lines. Below that, the second box with Pin 3 of 6 and Limited Edition of 500. To the right of the first two boxes is the last box that has the Official Pin Trading logo dated 2017. To the left of the two boxes is printed FAC-036223-17241. There are two posts, halfway down the pin on the left and right sides of the pin. The pin measures 1 3/4" by 1 3/4".
