Thank you for viewing. This is a set of 4 types of bridges for Plarail, including rare green mini bridges and a stand-type suspension bridge. The bridge, which is a dedicated part for Thomas's Outing 3D Bag, has a special connection part on one side of the track, so please check the image. As shown in the fifth photo, the connection part of the green mini bridge is missing. There is no problem with the connection.
