Ain't sure if this place is gonna have them but them's a bit thicker than regular pins. Kinda like this.

[It takes him a bit but he pulls out a pin, holding it up for Della to see. A large red hog sits in the middle against a red background. Holding it sideways, it is slightly thicker than a normal pin, with some small gadgetry between the front and the backing.]

Each pin can do it's own thing so it ain't 'sactly the same as the stuff you see around.
