The purpose of the invention is to improve reliability of a light emitting apparatus comprising TFTs and organic light emitting elements. A plurality of envelopes are removably stored within each binder. Teeth on the washer, positioned at right angles to the plane of the washer, are forced into each of the two metal pieces when the fastener is tightened, making electrical connection between the two metal pieces. The badge profile defines a size, type, and location of data to be printed on the customized badges.
